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?
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
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.
