The draft proposed to change many specific MUST and MUST NOT requirements
to MAY ignore.
It has been pointed out that the correct change would be SHOULD NOT and the
use of MAY is inappropriate
according to the definitions in RFC 2119.

Yet the WG continues to propose that these rules in RFC 7950 are purely
optional and can be ignored by
any implementation that chooses to do so.

Of course rules that affect backward compatibility and stability do not
affect the code that compiles a module.
They only affect the client code that attempts to use the unstable server
code.
