Comment:
I don't think there is a real value in documenting this discrepancy. This
is an SQLite caveat that will go unnoticed in most cases, leaving a bug in
users code. Adding a warning to docs will not change this or help in any
way.
Please first start a discussion on the Django Forum, where you'll reach a
wider audience, and see what other think. Assuming there is no way to
detect the number of rows in advance (as far as I'm aware there is not),
I'd close it as "wontfix" (or "invalid").
Marking ticket as need improvement pending discussion.
