It'd be interesting to know that in order to make a decision whether to enable
it or not.

But when enabled in xfconf, does xfconf handle *all* gsettings setting, and
nothing ends up in dconf?

I might have been unclear, sorry. When gsettings backend is enabled in xfconf
(whether with the current env var, or in the future if it's enabled by
default), what happens if two gsettings backends are installed/enabled (xfconf
and dconf)? Do they fight? Should we conflict against other gsettings backend?
If so, how is the migration handled?

Does this mean we'll lose any gsettings parameter stored in dconf? I don't
think it's acceptable.
