I agree. As a point of reference, the standard 1:25000 topographic maps of Spain produced by IGN, the national geographic institute, distinguishes between these two categories of water course. In the legend they are labelled as "curso de agua: permanente, intermitente". I think that is a good indication that this is a meaningful distinction. And I believe it is very similar to how things are already mapped in OSM. It is fine to give mappers ways to add finer details of seasonality, ephemerality and so on, but the basic distinction that already exists seems to be useful in its own right. As an aside, dictionary definitions of "intermittent" tend to say something like "occurring occasionally or at regular or irregular intervals" (example from Collins) which covers all forms of non-permanence, seasonal or otherwise. So current OSM usage of the tag, as well as being meaningful and useful, matches usage in everyday English.
