Yes, saw it.

One problem about this proposal is that it implies the proposed tag and 
intermittent=* are mutually exclusive.  This as said simply clashes 
with the current reality of tagging.

Creating a supplemental tag (ephemeral=yes or intermittent=ephemeral or 
anything else) would seem fine to me if it is well defined what it 
means and if there is a clear warning on verifiability (i.e. that you 
should only use it if you have realiable local knowledge of the 
ephemeral nature).

By the way about 100k of the 150k features with a seasonal=* tag also 
have an intermittent tag and the ~50k which do not include all the 
seasonal roads etc.  So seasonal=* is for water features mostly used as 
a supplemental tag to intermittent=*.
