GNOME 42 is due for release next week (2022-03-23). Release candidates of
most of it are already in either testing/unstable or experimental.

As usual, this includes a libmutter ABI break, from libmutter-9-0 to
libmutter-10-0. Suitable versions of gnome-shell and budgie-desktop are
already available in experimental.

However, before we can do this transition, we will need to get gjs 1.72
into unstable; that in turn requires mozjs91, which requires either a
transition to icu 70 (#1007905), or changing mozjs91 to use its vendored
copy of icu for now. Ubuntu 22.04 LTS seems to have opted for doing the
ICU transition.

mozjs78 to mozjs91 is only a "soft" transition: other mozjs78-dependent
packages (currently meaning cjs and policykit-1/experimental) do not
necessarily need to move to mozjs91 at the same time that gjs does,
although obviously we would ideally prefer as few mozjs branches in
testing as possible.
