Moving bindings modules to the Desktop moduleset won't make them less
second-class citizens as long as API that is not bindable without
resorting to language-specific glue code keeps being added to

Examples of this are GVariant (which affects GSettings) and GDBus, in
the latter this question was raised on gtk-devel but nobody showed
interest in how to make the new functionality available to bindings:

I don't think the authors of those APIs are to blame for this, because
they asked for feedback before merging and nobody cared about non-C
languages then.

It's nice that the release team worries about bindings because lots of
software is written for GNOME in languages other than C. But today we
are seeing a disproportion between the people who use bindings and
those that build them and it worries me a lot. What will happen to
those applications when old APIs such as GConf are not available any
more and GSettings is not available to their language?

An action more in accordance with the intention of making bindings a
first class citizen would be to require new API (with exceptions for
low level glib stuff) to be bindable by the introspecting bindings,
and also maybe some thinking into why the bindings landscape is in
such a mess right now.

Could be something like this be added to the criteria for platform libraries?

Presently, we have this stub for what is considered as "bindable":
