NO David, these would be changes based on current environmental  issues and
may be something that suits one intended use, but has unintended
consequences for other users. The former happens to platinum printers all
the time. We may find a paper that "works". And the manufacture will change
it based on it's intended use; watercolors, lith, monoprints, etc. The next
time you go to order it, it all appears the same, but a lengthy series of
phone calls reveals a change in this or that. sorry. .. Or as might happen
to glass. There was a glass used in printing that had a very specific
spectral transmission. PPG changed the transmission specs without consulting
platinum printers that were using it and having had our pieces of glass that
work fine as expected we saw no reason to order sheet after sheet since it
is just to hold the negative down, not travel with the piece, didn't think
any more about it. STOP!!! Someone else buys it and claims the glass doesn't
work . 
 same glass because it has the same name. NO  totally different from a
printers view point.
 
It can happen with papers too.  Same name, same general look but different
ingredients and the change takes place.    
 
Keep track of batch numbers while you can because they can help uncover a
change.

Eric, the changes you talk about to watercolor papers, wouldn't they
consist primarily of changes the manufacturers are forced to make in order
to make the paper characteristics come out the same in the aggregate from
batch to batch?
