If we were discussing a proposal I would agree, but replacing
waterway=drain by waterway=ditch + usage=drainage or sth. like that is
not such an easy task. We already have 800k drains. I assume it
requires a proposal with volting to deprecate drain, adaption of the
presets, perhaps a mass edit. Who will do all this? Is the advantage of
using waterway=ditch + usage=drainage instead of waterway=drain so
immense that it is worth the effort?

Thank-you for confirming that, Mark.
Personally I think we, in OSM, should stop with this folly of overloading
English words with meanings they do not have in any dictionary (be it AmE, BrE,
CaE, or whatever).
Both the "ditch" and "drain" words can be used to describe certain features in
English. The difference is essentially an etymological one, with one related to the process of excavation
(dig -> ditch) and the other to the function of carrying liquids away (dry -> drain).
If we want to precisely map certain characteristics of a feature we should do
it explicitly through a correct data model that takes into consideration the
particular aspect we are trying to communicate. We want to communicate the
information that a (small) waterway is lined with concrete? Just say that with
an appropriate tag, like e.g. lined=*, or lining=*. We want to communicate the
information that a (small) waterway is used to carry waste water away? Once
again, let's say that with an appropriate tag, like e.g. usage=* (please ignore
if the specific tags I put in the examples are not of your liking: not the
point here, let's discuss that later...).
Arbitrarily overloading words with meanings they do not have in the common
language is just a perfect way to Babel, that is a reduction in information.
