Request for a file picker standard.

[Carson Black]

This is already a thing somewhat with XDG desktop portals. Both GTK+
and Qt (and other toolkits) are able to take advantage of them, and
you can swap out the portals being used to switch between file
pickers, among other things.

See: https://github.com/flatpak/xdg-desktop-portal,

There are also a few more things to consider, such as backward compatibility and extensibility. As for extensibility, emacs with GUI shows a hint at the bottom of a GTK file dialog and Libreoffice shows checkbox for opening in read-only mode and choosing file version.
