butsnap list shows me

I don't use snaps or flatpaks and I haven't done anything in Discover regarding their "backends". They're as they came with the system. I haven't deleted anything related to snaps or flatpaks either. This is a clean install, not an upgrade from KDE neon 16.04.

Because a frameworks snap is rolled into the iso build with Neon, and installed by default by the iso.

It's a major reason that while supposedly being 'lighter', Neon iso is still 1.7G. The snap tar used in the build is ~600M IIRC.
