I don't recall the discussion (I recall the mention, but not the
discussion).  When not marked in some way to distinguish them from
normal symlinks which just happen to contain the variable-substitute
syntax in their link-to strings, I oppose them strongly myself.  But
with suitable marking (and I don't consider even FS-wide, much less
system-wide, suitable), I rather like them.

Lovely.  "I don't like this feature, so I'll break it to get people to
stop using it, even though I'm providing no substitute."  I really hope
that's not the true explanation.
