Alkaline buffer in photographic enclosures

It has been a long time since I had any serious instruction in
photographic conservation, but the opinion back then was that
buffered paper would fade cyanotypes (blueprints), and could also
affect albumen prints; but that it was unlikely to harm
gelatine-silver prints. The general production of non-buffered paper
for photo enclosures would seem to be a reaction of 'better safe
than sorry'--thinking twice, and not being too positive, is always a
good idea in conservation. Am I out of date, or would more
experienced conservators agree that buffered paper can be used with
many kinds of photographs?
