What Could Go Wrong
-------------------
Mutter is an essential component of the default Ubuntu desktop and for the desktop used by Ubuntu Budgie.

A severe enough bug could mean that people are unable to use their desktop version of Ubuntu.

Smaller bugs could interrupt people's workflows.

mutter is part of GNOME Core and is included in the GNOME micro release exception
