So has 155mm Artillery, i'd also prefer that not be used in city limits.

So should we develop everything using the criterion "will it prove useful in an active warzone" ?

To be fair... a non-trivial percentage of the major breakthroughs in human science/engineering were developed to have some form of impact on an active warzone.

As that criterion would sink most of the ad-tech industry, maybe it actually has some hidden merit? ;)

Concorde was also useful in general, yet thanks to sound breaking noise was not allowed to fly over land supersonic.

Now imagine 4, 8 or bigger combo of flying vacuum cleaners in 3am. People are going to eat you alive.
