It's good to re-visit the reason for Rule 3 in the first place: to try and convey to a global, multi-lingual poker world with alot of new players entering every year, that the responsibility for getting their intended betting action right lies
primarily with the player. This is consistent with the language adopted in 2009 that "it is player's responsibility to make his actions clear".
In that context, including some unmistakable "time honored" gestures definitely makes sense...
These specific words and gestures are there not so much for their own sake, but to provide examples of how best to conduct an event for maximum clarity of action and minimal problems regarding how to interpret action.
btw, can't resist this one: whenever a player is facing a bet and says "make it ___X___", that's the same as saying "
raise to a total of X". You never say "make it" when facing a bet if you just intend to call

HOWEVER, here's the problem with "make it".... Let's say I'm facing a 1000 unit bet, and I say "make it..." then hesitate. Have I locked myself into a raise? IMO I haven't. I could just then say "Make it... 1000", and call... the TD might grumble about my disruptive choice of words, but I think by rights my call would stand. For that reason IMO, "make it" doesn't reach the same level of clarity as "raise".
