Actually, <> works and s1*0 does not always.  Example:

\new Staff <<
  \new Voice = "notes" { c'4 d' e' f' }
  <>^"blah"
  \lyricsto "notes" \new Lyrics { do re mi fa }
>>

=> compiles and renders perfectly fine.

\new Staff <<
  \new Voice = "notes" { c'4 d' e' f' }
  s4*0^"blah"
  \lyricsto "notes" \new Lyrics { do re mi fa }
>>

=> triggers warnings and wrong output.

I've adopted it in my scores the minute I've seen David's post
suggesting using <> iso s1*0.

Even though at first sight it seemed to work well "by chance", it's easy
to explain its meaning in the documentation, as there is understandable
semantics behind:  a chord with no note takes no time.
It's not a syntactic hack.  The perlization argument does not hold.
And it's already there!  Apart from the few minor issues detected by David,
it works on any version.  So indeed, why add new syntactic structures when we
already have it?  The parser does not need new special cases, after the
efforts for reducing them.
