PLR2004 has a few allowed numbers including '', 0, and 1. #9964 has fixed a bug so that 0.0 and 1.0 are also allowed. There is already an option to ignore certain types of variables from the check. I'd like to request an option to extend the allowlist. For example, I have a library where 2 (and 2.0) are really common and I don't want to use a global variable for it. So I ether need many noqa comments or to disable the check entirely.
