It may not work anyway by default for folks who install Builder since I 
assume Builder tries to use SDKs that are only available in a repository 
that doesn't follow the FSDG.

Sorry to hear your experiment didn't work out; that sounds like a really

I'd be OK with having a builder without flatpak support. Too bad there 
isn't a "build with Guix" backend. Maybe one day!
