Would a tower with triggers that are a bit too calculation-intensive to be practical for multiple players (too much slowdown with that many of the tower built) be acceptable?
It's not necessary. If it contributes to the implementation of your code (for example, having a raw code there that could change depending on the map) then it should be included to make it easy to import. However, if nothing will need to be customized to get the code functioning, then it is not required.

Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
