Doug, if people want to do it, I would have no problems adding a
comment to any construction (including built-in productions) in
ABNF that has proven dangerous warning people that they should
understand it and its consequences before they use it. I would
have no problems if that note made it clear that use of LWSP in
a context in which it could end up on a line by itself (in a
context in which "lines" are significant) can be particularly
problematic.
I see those options as very different from deprecating something
that is used successfully and correctly in a number of standards
and incorporated into them by reference. Since it is in use,
and the definition is actually quite clear, deprecating it seems
completely inappropriate.
