It seems that older rockbox builds aren't available anymore, even on archive.org, and users have reported glitchiness and stuttering with the recent versions also on the Rockbox subreddit. Given that even the latest version still exhibits the unresolved issues I've already mentioned, would it be reasonable to provide official builds from a january commit that doesn't have the data abort bug nor the sluggishness caused by its 'fix'?
Again, I've been using 00c7817c9c326368c2cd89f1e786584283935c9c from 2023-01-12 ("[BugFix] playlist.c DIRCACHE stop scanning when changing indices") on several devices, both vintage and modern, without any single crash or hiccup.
I'm also willing to provide those builds myself if the devs aren't, as I've already compiled builds for all my devices that work perfectly fine.
