I agree with remove of "seasonal"

I disagree. Waterway where water is missing with some regularity is
stil intermittent.

I completely agree. Waterway may be intermittent without making it
seasonal. intermittent=yes do not imply seasonal=yes.

My "it depends on location" applied to "given the weather does not
conform that well to the 'season's".

And I would not be against removing them. I am only against restricting
intermittent=yes to random lack of water.
Stream that disappears every summer IMHO should be tagged as
[waterway=stream, intermittent=yes, seasonal=yes].
In case that using intermittent for "waterway does not have a permanent
flow/waterbody does not have a permanent presence" is clearly bad we
need tag is needed to cover this information.

Why? What is reasoning for this?

Seasonal waterways by definition have no permanent flow. Current
practise is to tag such waterway as intermittent=yes. Is there a really
good reason to invent a new tag to convey this information and
deprecate current meaning of intermittent=yes (that is used over 900k
times, with some data consumers already using it)?
