I see that this codebase mentions the SteamLinuxRuntime_sniper-arm64 compatibility tool. That tool is being phased out: there aren't any released games that use it, and if unreleased games have arm64 binaries, they should target SLR 4 (SteamLinuxRuntime_4-arm64) instead. Similarly, Proton 11/Test/Experimental already uses SLR 4, so it's likely that any arm64ec builds from those branches will use SLR_4-arm64.
New versions of sniper are likely to stop generating arm64 files and arm64 containers in the near future. I'm not sure whether old versions will continue to have them, or whether the old arm64 files will be cleaned up to save some storage space.
I'd recommend removing references to SLR_sniper-arm64 before that happens, to make sure this tool won't regress.
