I'm not sure a change to the API is justified presently (same does go
for 'properties' really, but as it was only a couple of lines, it
didn't seem too intrusive).

My recommendation is to handle this in-house (i.e. locally in-driver)
for now.  When (if) more users adopt the practice, then we should
consider to draw down on line numbers and repetition and make it part
of the API.
