Launchpad should require water.

Water's an essential part of every rocket launch.
Not too hard to implement, although i'd understand you guys have no time to devote to such minute details. However, I know that the sight of a whole water system around the launchpads would make me incredibly happy. Suspiciously happy.
I always feel like the rocket feels a little bit too quick to setup.

It can be added as mod.

I don't think missile silos use water though. According to this video they use acoustic dampening tiles

Water can be used to suppress sound I guess. In no way it is an essential, or even required part of rocket launch. Soviet rocket designers placed their launchpads in the middle of dry steppe, and I guess they knew something about rockets seeing as we still use their designs today.
