Reserving rights for formatting specifiers in SD-8

[cor3ntin]

We need a paper to update SD8 such that we make it clear we can

• add new specifiers and options to the format spec of any formater
• extend other grammars such as regexes, format, printf, scanf, strtime, etc functions

This is a good idea, but this is a LEWG/LWG issue, not a SG-16 one. This should be raised with those groups.

I agree also. In addition, though, for compile time things that expand as templates, we need a concrete mechanism in mind. While we don't specify implementation techniques of the library, we need to make sure it's implementable. This probably can be done with inline namespaces for something like format or any CTRE. I think printf and friends already reserve %* in their grammar?
