Yes, we can be more fine-grained, basically:
* 16.04 -> Min and recommended is 2Gb (this was bumped when our 16.04.x 
maintenance image started to include snapd)
* 18.04 and onward: 2Gb min, 4Gb recommended.
However, if we bump recommended in that file to 4Gb, GNOME Boxes will 
set that as a default, which we aren't really keen on (the 4Gb 
recommended is a large estimate for people using a lot of tabs in their 
browser, which isn't our GNOME Boxes typical usage we are targeting at).

Does it makes sense?
