Yes, sure. It is fine to reuse an existing user option. Though reading
through its docstring and the code, I cannot tell what this is doing

On my end, I have that option set to nil, but exported headings do use
their CUSTOM_ID.
It seems it was broken by
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=5e9953fa0e
`user-label' is set to CUSTOM_ID when it is set, so checking the
variable is not effective any more.
Nothing is broken. CUSTOM_IDs for _headings_ were used unconditionally.

Independently of this variable, however, CUSTOM_ID are always
used as a reference.
My bad. I believed that this option is (or was) necessary to get anchor
names as CUSTOM_ID, but I have tried Org-9.1.9 and I see elements having
id attribute with CUSTOM_ID values.
