You can use it in a "MUST NOT generate, MUST accept" section
about obsolete syntax, same idea as obs-FWS in 2822 + 2822upd.

The LWSP problem are "apparently empty lines" in the header.

For mail and news the sound solution is FWS excluding obs-FWS,
folding is okay, but each folded line has to contain non-WSP
(= not only white space).
