As a practical matter, no. You either comply with the rfc or you don't.
If you do NOT comply, then you may have interoperability problems with
those servers and clients that do comply. The goal of all IETF RFC's
is to ensure and encourage interoperability. People won't buy or use
products that don't interoperate as they obtain products from many
different vendors. A vendor that doesn't interoperate with products
from other vendors isn't likely to stay in business very long as clients
won't buy products that don't work with other products that they
already have.
