The less true the game ends up being to the actual ruleset the better.
DnD is absolute trash for combat. Its poorly balanced, it has no interesting mechanics, it does absolutely nothing thats worth playing. Everything that is interesting about it comes from unique actions of the player which are not part of the core rules.
Combat is a sidenote in any decent campaign. There are several modules and games(tabletop) that do core combat rules way better.
FFS dont listen to people asking for "1 to 1 implementation". Its awful.
The only people that ive seen react like this with regards to the rules are the people who dont actually READ the rules and dont even know what options are open to them. They just want to mimic the voice actors from Critical Role and think dnd is only about stage acting or something.
I dm for groups and play in a few. Combat can be quick and sweet if everyone at the table knows the bloody rules and its muddy and slow in groups that dont. Some groups have people who prefer the roleplaying part and thats fine. But combat is and always will be a part of dnd. I swear if I hear 'the rules are just guidelines' as an excuse why a DM wont follow basic rules and to restrict players or 'this is homework the game' I swear il bloody toss my desk out of the window.
