Proceeding his GhidraOrbis Plugin, PS5 homebrew developer astrelsky recently made available a proof-of-concept poc.zip pack consisting of a send_elf.py script, spawner.elf and test_elf.elf including libhijacker source code for those in the PS5Scene to try out via port 9030 on exploited consoles. 
Download: poc.zip (118 KB) / libhijacker-master.zip / Libhijacker GIT / WIP / PS5PoC_test.zip (138 KB - includes PS5 PoC.exe) via Cedsaill2 / Libhijacker Fork & GIT via SiSTR0 / Libhijacker Fork & GIT via illusion0001
This comes following initial news of homebrew on PS5 soon via @zecoxao on Twitter for PS5 3.xx-4.xx consoles, and below are some of astrelsky's messages via Discord on this PlayStation 5 homebrew release:
I literally just slapped a test sample and threw it in there with a few line readme
Won't be surprised if it doesn't even work
Idk what happens if you try to use stdout on an elf loaded in WebKit
It's just a dummy ps5sdk I had setup to keep a different tool chain cmake to use for the test elf
I didn't include the source because it wouldn't be build able without other things yet
Yes, redis
I left it full of debug info on purpose
Wait until you see some of the comments in the code lol
It's just a poc, if even that. You can't do sh!t with it until it's made all pretty and integrated into the *** somehow/somewhere
That's why I didn't release the source yet
I spent most of the day going down a rabbit hole trying to get exceptions to work
It's running in its own process
And is using so files instead of pulling everything from dlsym
You'll be able to read/write to other userland processes with the api. Memory protections are ignored.
The process is technically local to redis (using sce spawn local process from the redis server process) so it a daemon
In theory the same methodology can be applied to a game process from this daemon
It might actually be more constrained wrt resources
I don't really know
I'm out for the night
You are thinking in the right direction
You can patch shellcore and games and anything userland too. Just not the kernel
Almost anything in userland at least
I'll now be awol for the next 2 years
Finally, from the included READ.md: poc
send elf using send_elf.py
once sent, if successful it will listen on port 9030 and will dump the kernel data
me very lazy, explanation skills D-

Q: HEN?
A: No
And from the libhijacker README.md: Project name is temporary
This repo will likely be short lived. I got tired of waiting and wanted to upload it somewhere. Proper credits will be attributed later.
The 'libhijacker' is a valid (albeit partial) method towards running homebrew, you'll have to be patient as usual, until someone completes big-app support. This is the next step to launch something useful (actual 'homebrew' as you know it on PS4).
Bloodborne Running at 60fps on PlayStation 5
PS5 Homebrew update: New spawner.elf released by Astrelsky. Should work with WebKit attack method.
Gravity Rush 2 Unofficial 60 FPS Patch at 4K60 on PS5
Bloodborne at 60 FPS from Manfightdragon on a hacked PS5 (Firmware 3.00-4.51)
Red Dead Redemption 2 60 FPS on hacked PS5 (Firmware 3.00-4.51)
The Last Guardian (PS5 60 FPS) Full Game
Removed 30FPS Cap in Demon Souls (Cinematic 30FPS Mode)
Crash Team Racing Patched to Run at 60FPS on PS5
The Last of Us Part 2 and PS5! No 120FPS Output Though, Just 60hz and no VRR (on 4.03)
it goes without saying this but, even if game loading does become a reality in the near future, there is the issue that sleirsgoevy payloads only decrypt ps5 demos and ps4 games correspondant to the ps4 *** version of 4.03 and below versions.
this means you won't have ps5 game loading from anything other than demos/freemium
