I never understanded this kind of attitude ...
I wonder how exactly the is encouraging "cheesy tactics"
You don't "understand" because you don't really try.
Being able to sit comfortably in stealth and join the combat at discretion is a mechanic that encourages and rewards cheese.
Being able to use shove as a "bonus action-fueled human catapult" is a mechanic that encourages and rewards cheese, AND through the AI behavior forces it on you even when you aren't the one using it.
And so on.
And the reliability and solidity of any game system should NEVER rely on the player exercising self-restrain on the options available to him, anyway.
Ideally it should be the task of system and encounter designers to find all the ways to poke holes in the gameplay and fix them.
