global UI freeze exception for high contrast app icons (?)

[Frederic Peters <fpeters gnome org>]

Hey,

3.16.0 is out but some applications do not have high contrast app
icons yet, or have one but it's not being used for some reasons (it's
the case with Videos).

  https://wiki.gnome.org/Initiatives/GnomeGoals/HighContrastAppIcons

I'd rather like to encourage maintainers to apply the patches when
they exist, even for 3.16.1, even as there's an UI freeze in place
(the appbar is rarely in application screenshots).

What do you think?
