I have a 3rd-party repo (packages.sil.org/ubuntu) and I can confirm that this change enables Gnome Software to work correctly with my repo. Previously my apps weren't showing up, but now they are.
I built a copy of appstream-glib_0.5.13-1 with this debdiff applied, installed it on a xenial system, and everything works nicely.
