Of course. And it proved to be unmanagable, the larger the card
catalogs got.
But a fine-grained classification might not be exactly what we need,
for the purpose of ranking. The 3-digit Deweys might be just right
for ranking or grouping of results. Even these are outdated, yet this
level is more robust than the longer numbers.
The 3-digit Deweys might even be uncoupled from Dewey as such and
form the basis for an updated, new, very broad classification, just for
ranking and grouping. Most legacy data do have Deweys, so this would
be an obvious starting point. And where there is no Dewey, there's
probably an LCC, and it might be translated into an appropriate number.
Tables for that task exist.
