I'd be all about it. The 20ga is no slouch in terms of taking Whitetail deer and home defense duty and a lil less punishing on the shoulder recoil wise for any smaller stature or recoil sensitive men/women. Only thing that would make me a lil sour on it is not being able to find a good selection of shells and paying considerably more for a smaller shell with less availability, (see .410 as well). But the 20 ga is leaps and bounds more available than .410 but definitely not where 12ga is.
I remember 5+ years ago I could find and buy 20ga in just about any load and there was plenty of it, selection, availability, etc and it was cheaper than 12ga but it's all flipped upside down now. I used to buy 100 packs of #8 20ga for $20.
But as far as having a good solid hunting/HD gun that isn't gonna be a high volume shooter I can see where the 20ga still makes sense. It is a lil smaller, lighter and doesn't have a harsh recoil and would love to come across one honestly. I would like a .410 as well but finding shells is a crapshoot and those guns tend to be finicky whereas the 20ga and 12ga seem to be equally reliable.....
