I don't know why it isn't added to main repo. I see that cragson went inactive on ps5 hen after initial release
There are backports like in the ps4 scene. Every game that requires new filmware can be backported to play on 4.51. Also one month ago there was release of new hypervisor exploit for firmwares upto 4.51. Thats why linux is possible on you...
I thought that shadowmountplus load kstuff automatically? So you are saying we don't need kstuff on 4.xx if we load ps5 hen and want to play ps5 dumps?
