In further testings I observed a disadvantage of the approach via
Stem.positioning-done:

If a user has different sized note-heads in a chord, the zero-value is
not a neutral element.

See:

{
  \once \override Stem.positioning-done = #(positioning-done '(0 0))
  <
   \tweak style #'slash
   c'
   g'
  >2
}

To fix it, I think one would need to reimplement (with hooks to
customize the behaviour) the note-head/stem-placing-procedures in
scheme.
Apart from my lazyness ... it feels like overkill.

Thus I implemented a different code in the lsr-snippet.
Replacing the stencil-calls (only needed for getting the extents) by
the grob-extents.

WYT?
