I think it's a little late to come to this realization. Note how my
prior attempt at fixing 61570 was delayed for more than a month so that
a proper sanitizer can be implemented and would have had a better user
interface than what you are currently proposing.

Need I remind you that the original concern was about backwards API
compatibility? Yes, accepting strings and doing things with them is
broken for the reasons you mentioned and there should be a deprecation
warning about this. But not heeding the user values is silly and you
should still set those vanity values for the sake of vanity itself.
Cheers
