Not per https://src.fedoraproject.org/rpms/xsane/c/2cc8bf4 (Drop GIMP plugin for Fedora >= 41, 2024-10-13) and the follow-up which fixes the reversed values in that commit.
I would guess that's because gimp-3.x and the xsane-gimp plugin don't play well together or, more optimistically, that it's somehow not actually needed anymore. But I don't use xsane and haven't done more than poke the package history quickly.
Well I do, and gimp no longer knows anything about xsane. Well, that answers that.
Gosh, I get reamed out if I accidentally add some codez that break older compilers that still come with older EL/LTS versions. Enough said.
