Bug#994944: libgtk-4-bin: gtk4-broadwayd not available

[Nicolas Delvaux]

According to the Changelog (version 4.4.0+ds1-3), this was done on 
purpose:

   * Disable Broadway (HTML) backend.
     It isn't clear whether this is used in practice. If we disable it 
now,
     enabling it later if requested will not be an ABI break, but if we
     enable it now, we have to keep it enabled indefinitely.


So here we have Cambalache[1] as an example of the Broadway backend 
usage.
There is also my project Deckard[2] that is used to help testing GNOME 
translation.
LibreOffice used it in some PoC, I don't know if it's part of the 
current LibreOffice Online.

But Broadwayd can also be used standalone, which is hard to quantify. 
There are a few blog posts with positive feedback on the feature though.

Now that more and more GTK projects are being converted to GTK4, the 
lack of the Broadway backend will only become more apparent.


TL;DR: +1, please enable Broadway for GTK4!

PS: gtk4-broadwayd may be split in a dedicated binary package if we 
worry about it not being used much. And it would get us some POPCON 
stats.
