You would encounter little resistance if you were merely adding optionality.
Why are you trying to remove the ability of users to set a limit for OP_RETURN if they want to?
You are not adding optionality...you are attempting to remove it.
If somebody wants to throttle non monetary data from passing through their own node, you are actively making a change which prevents them from opting out.
You could easily add the optionality you want WITHOUT removing people's ability to opt out.
There is absolutely no justification for removing this option other than as an attempt to force people to adopt a feature they would not adopt voluntarily.
You are also gaslighting everyone with this condescending nonsense.
