Well we can select integer or uneven stretch in regular MAME, isn't that the same thing ? Anyway what I'm thinking of already exists in the GUI while ingame you can press TAB and manually stretch V and H, but it's almost impossible to adjust to integer with the naked eye (edit: but it does allow to stretch out of bounds). The damned RA makes it immensely more simple by having a custom scaling option where you can set 2x, 3x, 4x etc for V & H at will -> MAME absolutely NEEDs this I believe. Seriously even if it often costs the user little black bars or some lines left out of the screen space; a properly scaled image looks sooooooo much better than any lousy uneven stretching. And don't talk about buying a proper screen for the only 'nearest integer' setting currently available in MAME, I don't want to use a magnifying glass to play as it only very rarely fit well on most pc monitors.
So that would be good, also a less lousy than bilinear filter available by default would be nice, something similar but more gentle/less muddy combined with integer scaling would be a freaking win, and no need to bother with shaders and stuff.
I've always felt the official MAME could use a couple simple 'feel good' things like that to make it more enjoyable by default so that people wouldn't have to think it's lacking and go seek/beg alternative build or frontend makers for all kinds of modifications.
