Thoughts ... (take on Hobbit like theme - one key to rule them all...)
As both intermittent and seasonal are all render the same .. why not
combine them into one key as well?
non_perennial=seasonal/intermittent/ephemeral/summer/spring/winter/autumn/intermittent_summer/ephemeral_summer
etc
I note that intermittent is taken by many as 'I know it is
non-perennial' so it may be appropriate to have a non_perennial=yes for
the more common mapping value.
???
Well? Is that a reasonable idea?
It could be implemented as a mechanical edit on
seasonal 1:1.
On intermittent=yes ... as non_perennial=yes with a request to determine
a more specific value?
On intermittent=/season/ ... as non_perennial=intermittent_/season
/These could coexist with the present tags while people changed over.

You can do *exactly the same* with my new proposed values for
intermittent=*
No need for a new key, I think.

At the moment developing a system to render seasonal values on

this would add some new terms. Not too hard but does add to things.
Also developing a system to render the ephemeral key would add some
complexity, probably more...
Not certain about ephemeral being subservient to intermittent.
If it is not there all of the time, than it is intermittent.
If it doesn't last long, than it is ephemeral (/but then it is not
there all of the time and thus it is intermittent too/).
The primary motivation for me is that a water feature with
intermittent is more likely to have water, even it I have to dig a
meter or two for it, than a water feature with ephemeral.
I don't expect a 'normal' map will tell me this. But a desert map
should.
I would map the ephemeral river banks/courses.
But then the places where water pools to form more permanent water
sources I would as natural=water, intermittent=yes. In this way they
can be distinguished as a more probable source of water.
Some satellite imagery shows these .. but then some shows the area
just after rain! So it requires some judgements.
I'll add this as a rationale ...
