No. The main reason is that the patch introduced a dependency which
should not be there. Papering over it with a .pc file changes nothing to
the fact that third-party projects will now be unable to use the header
without installing glib first and that there is no good reason for that.

I know you were talking about spice-gtk, but would the spice patch
below be what you had in mind?
