Try replacing this one with ly:stencil-stack.
Do you mean ly:stencil-combine-at-edge replaced with ly:stencil-stack
? I tried it, but the result is the same (with \lower #offset inside
the markup)
thanks,
Paolo
What version do you have? This works over here;

Note that ly:stencil-stack will still prevent the stencils
from getting too close, while allowing them to get farther
from each other. I inferred this was not an issue from
you problem statement that "sometimes the text is too
near to the hairpin". If it is, you can use ly:stencil-add,
removing the line with "Y dir", and put \lower in each markup
as appropriate. You can also keep the original code and use
\with-dimensions, or \with-dimension from
https://lists.gnu.org/archive/html/lilypond-user/2020-12/msg00196.html,
to give the "moltissimo" text a different extent
altogether.
