Maybe you cannot use a switch to limit current. I can, and so can BMS designers.
That's not our problem.
Again, semantics. You want to pretend that current limiting needs to mean "constant current", when it does not. Anyone with the ability to use a full vocabulary would use the word constant instead of limit, if that's what they meant instead.
If you want to be pedantic and accept that it's limiting current to zero, that is still the opposite of unlimited current.
Maybe you just need a different hobby?
I will concede that it doesn't fall within the neat and tidy vocabulary you want to use, but it also does not fall outside of the more general communication of purpose.
Binary or shades of gray? Your topic has no useful purpose. That's binary to me but should at least be shades of gray to you.
