Nobody shows up to do the work. Red Hat funds 1 or 2 people to work full time on GTK, plus a few part time. Igalia funds some part time developers. Similar story for other companies.
These companies are primarily Linux affiliated, so what real incentive is there to put in any work? A community volunteer recently opened a PR to add Android support, and Christian Hergert (Red Hat) worked on the new macOS renderer as part of his job, but we can't rely on inconsistent contributions for alternative platforms. If you like GTK, and use alternative platforms, think about contributing.
It's a shame that Gtk doesn't have first class support for other operating systems.
I used to be very optimistic on this, but it's just not a focus for them.

Given how hostile GTK+ has become for anything that is not a GNOME application I'm surprised that this hasn't become the norm yet.
Also Qt makes it way easier to port applications to other platforms.
How has GTK become hostile?
