In the past, I've seen single side posts on the majority of GA's freeways, and I do believe that they're still out there. Even that would be better than the current practice. The only acceptable use of one sign on a full gantry would be for APL's and diagrammatical signs.

Yes. And I've never seen those single post signs raised that lead to an exit here in North Carolina, although there are a few raised posts for mileage exit signs like here in Wilmington, this is the only one I can find:

The thing that Georgia does that I wish more states would do is, on freeways with 2 or 3 lanes in one direction, instead of a cantilever they simply mount signs on the side but at overhead height. E.g. https://goo.gl/maps/cpsvKt3V5G8pTzQF8

North Carolina does it sometimes... There are some along I-85

One could do what Ohio would occasionally do in the past and mount a single sign on the side but on a cantilever over nothing.    https://goo.gl/maps/yZq9RzLLR3XSn4Dj8

Mass replaced full gantries with cantilevers for 2 full-size BGSs in places on the Mass Pike also.  https://goo.gl/maps/75uCHBBwFCUu1FdU6  (It is interesting that the median mount for the old gantry wasn't removed fully; the uprights must not have wanted to un-bolt or were frozen in place, because they just cut them off and left the stubs.)

They did the cantilever eastbound as well (https://goo.gl/maps/ghh6XmY2Zir9wR7W6) and street view came along at just the right time to catch the old signs, still on the cross member, sitting on the side of the road.  (It can be seen from the EB gantry post-sign-removal that they just cut the vertical members here too.  Easier. https://goo.gl/maps/kF7qVcSJSgBf4Aot9)

It seems like they only used to cut off gantry poles when they were totally immovable, like this remnant that has been in the median of 128--I mean I-95, for over 2 decades now.  https://goo.gl/maps/crjLMU5uf285LGdu9  The larger metal circles were the two parallel vertical parts, and the smaller one was a diagonal one as there were diagonals zig-zagging up between the two verticals.  That gantry was removed and replaced with a full-dual-carriageway-width one which when new had button copy numerals for 93 (so we're talking a while ago); the full-roadway gantry and signs have been updated again but that bugaboo of the 70s gantry having a few feet concrete poured around its base has left the cut-off poles there until whenever they redo that median wall (which probably will happen eventually, but not for a while knowing Mass).

The single chorded poles are definitely uglier compared to the  truss cantilevers and full truss gantries that NCDOT uses. Sometimes the full gantries are triangle or square!

As a Georgian roadgeek, yes, they should.

North Carolina started installing two signs on a cantilever recently. They started something in 2013 or 2014 I think, they probably wanted to try something more economical. Prior to those years, they all used to be on a full gantry. They use full gantries if necessary for 2 signs but other than that, they use both cantilever and full gantry for 2 signs. But if it's 3 signs, then definitely full gantry. Funny how Tennessee did the opposite.

This is interesting that TDOT used a full gantry to mount a single sign on. Unless they are following Georgia's rule? I honestly don't know though.
