It does not output any ink.

I'd use point-stencil, but that engages padding and similar if
necessary. The concept of having ink but no influence is shady to
LilyPond.

The latter can be done with
nodim-markup = \markup \with-dimensions ... \etc
The former is too mixed. You could try something like
\nodim = -\tweak Y-extent #empty-interval \tweak X-extent =
#empty-interval \etc
to return it to the music realm only instead of some music/markup
mixture. But no guarantees it does something sensible.
