It is not.  Long story short: folding a headline works by adding a
text overlay with the invisible property, and finding the end of the
overlay works by finding another headline of the same level.  So there
is no nothing of "jumping" by N subtrees.

Still, you can fetch the number of invisible headline in a folded
subtree *afterwards* -- I assumed this is what François' code does.

This could end up in a minor mode or simply a feature that people
could turn on and off.  But beware of the efficiency: with many
headlines, the folding features of Org combined with this feature
could become quite slow.

No problem, that's part of the game.
