For a “system-level” package, GVFS has an unreasonable footprint:

The main issue is the dependency on webkitgtk:

One way to address it might be to build libgoa-backend and
libgoawebextension separately from the main libgoa.so, or to have them
in a separate output.

However, I’m not sure how libgoa-backend is supposed to be used.  It has
a .pc file, which suggests applications that need it explicitly link
against it (as opposed to having it dlopen’d), but I couldn’t find an
example.

Thoughts?

For inspiration, here is Arch Linux's pkgbuild for libgoa, which is 
split from gnome-online-accounts:
