If you like adding home brew on the fly during game it is your Dming style. I wanted to emphasis that players will usually remember and repeat all those new tricks in a constantly expanding rule set.
So now making a ruling is "homebrewing on the fly." I find that funny - but even if it were that'd also be fine. I am not worried about my players emulating a less than efficient tactic when they feel it is needed.
