I have enough confidence that if not all at least most versions
(especially newer versions) have that feature.  So I would place 1.8.7
as dependency.  I'd say you are pretty safe since the newest versions
definitively have it and the percentage of old 1.8.7 versions
installed is probably rather low.  My 0.02EUR.

Kind regards
