In his 1968 Basic Photo 'The Print', my bible for some years, he says that
it is needed on many 'modern papers', especially when you increase
development times to get richer tones, as this results in some veiling of
the whites. It's one of the steps ('Clearing the Whites') in his standard
processing sequence rather than a special treatment.

I haven't bothered to do it for years, but I did make better prints back
then. I normally put this down to changes in paper, but it could also be
because I got lazy over things like this.
