That's not a general rule at all.

FFS, I'm posting a series adding a new feature, which depends on first
addressing a few related bugs. I post everything together so that it can
be evaluated and tested together. That's perfectly fine, and not that
different from how we post driver and dts changes in one series to
facilitate review. Some maintainers don't like that either, then we deal
with that.
