Should we make org-fill-element respect the selected region and not expand the selection to the element boundaties? (was: Bug: org-fill-paragraph [9.3 (release_9.3 @ /usr/share/emacs/27.1/lisp/org/)])

While I understand that the current behaviour is unexpected, it is
internally consistent within Org for different kind of Org elements:
paragraphs, source blocks, comments, tables etc. For all the elements,
Org effectively expands the region boundaries to the beginning/end of
the first/last element in the selected region.

If we do decide to change expanding the selection to the element
boundaries, it should be done across all filled element types.

It will also be a breaking change.

Should we go for it?
