IMO this is the right question to ask, even here.

Probably it would be more informative to describe which features you
need that are implemented "incorrectly".

Reality check: RFCs are not government-enforced standards. There are many
sensible RFCs that never got implemented widely, or nearly at all, are
implemented partially, or there are widely deployed not-fully-compliant
software systems. If your client software requires a feature that's not
widely available, you're just limiting your audience.

You may try to find a different way to achieve your goal using the
features that are widely implemented. Real, successful software packages
very often contain options to do some quirks in order to stay interoperable
with existing noncompliant implementations.
