Fair point. However, in any context where "pages" could be a list of
pages, you are unlikely to need a separate "pagecount", as it's just
the length of the list. Maybe it's the number of pages you're _going_
to need, or something. But it's nearly impossible to judge without
context.

Maybe "almost always" was too strong, but in real-world contexts, I
don't often need to specify that something is the "number of"
something.
