No. We've missed removing something that should have been removed a long time ago. Back in the days, we had plans to make house building a lot more free form by placement of individual wall sections. The problems of doing so: checking for house integrity, coming up with rules for collapsing crooked houses, disallowing unreasonable house forms and god knows what else were, however, deemed insurmountable at the time. The ctrl+a command is a remnant from that time. We might return to the idea at some point, but it is about as low as things can get on the list of priorities.
