Yeah, sorry man... there are way too many complications with it, and the general consensus is that destructible terrain is pretty much frowned upon. Where's the fun for players who join a match halfway through a map's playtime and when everything's already been destroyed?; have it regenerate? Objects can't even be destroyed in Soldat due to its coding in the first place, and MM has already stated that the map format change will not be changed. It doesn't seem that many people would like it even if all the raw glitches were solved, so there's not much point in trying to achieve this; I'll be locking this, then.
Don't let this discourage you, though; just make sure you check out the sticky at the top of this section before suggesting. Thanks.
