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.

There is no single definition for LWSP across many documents. A statement that both warns about possible adverse effects and that a different label should be considered for new drafts solves both the problem of conflicting definitions AND inappropriate promotion of this construct. A statement that LWSP is deprecated does not imply it is now obsolete. Other documents which have referenced this document will simply find the definition deprecated. New drafts should consider either creating a more appropriate definition, or use a different mnemonic with their desired definition.
