For me, this change would also break the otherwise awesome mod, that's why i've tried to collect the best reasons which came into my mind, and posted it into the suggestions forum and hope that some people will comment there, because if i'm the only one who points that out, it won't have any weight at all.
For anyone that doesn't like the limit, there is an option in skirmish games which allows us to use the old unit limits at least, just wanted to point that out.
