Hi Ilya,
I'm glad to see your effort on this!
I'm not convinced that this deserves to be its own targeted thing rather
than a more general request validator PSR. A more broad request validator
PSR could handle more types of validators and validate the entirety of a
request rather than just this one small aspect of request validation. For
example, on a registration form submission I might want to validate the
provided email, password, name, settings, etc. and I think by focusing on
such a narrow swimlane for this might hinder future efforts to build the
more broad PSR I'd prefer to see.
Can you speak to why this should be a standalone PSR and not a general
request validator PSR?
Thanks,
Korvin
