What was in the original import can be seen in:

There's "gnis:ftype LakePond" but no "water=*".  As regards the "new 
scheme" anyone processing water data is going to have to cope with 
existing data containing "natural=water" and "waterway=*" anyway, so 
this proposed change (removing the "Lake;Pond" tags) doesn't introduce a 
new problem.

Let's not forget - it's an import - no-one has actually surveyed these 
water bodies so we don't know whether a particular one is a best 
described as a "lake" or a "pond" (that's assuming there's nothing that 
can be read from "gnis:fcode" of course, and even if it could, that's 
still an antique survey presumably about as relevant as the TIGER data).
