I think it's appropriate to include a note to
- explain the problem caused by LWSP
- suggest that it's included for backward compatibility and it's
probably not something that should be used in new specifications

I'd stop short of removing LWSP (for backward compatibility reasons) or
forbidding its use in new specifications.  ABNF is just a notation for
describing a syntax, and the spec shouldn't try to artificially
constrain what kind of syntax can be defined.
