As an option we could remove the more "controversial" locale part. '0' and 'P' seem OK and there were some requests for the former.

Yes, please!

BTW is there an implementation?

I didn't say that I like the locale part. I agree that it's a bit hacky but I didn't feel strongly enough to object to the whole paper, just called it out.

Allowing locale-dependent printing of pointers in order to get a more
readable representation seems a hack to me. If the user goal is a
more readable pointer representation, we should be providing a direct
way to obtain it, not something that abuses the localization mechanism
to achieve it indirectly.
