I'm not against such a feature. I'm against the fact that is enabled by
default, in such a way that it's next to impossible to disabled it
without affecting some other part of darcs or the other applications.
A --pager option to the help command would solve this nicely. It should
default to off, so the old behavior is possible. At the same time anyone
who wants a pager by default can add to ~/.darcs/defaults a line like

Having to always pipe to something is not a good choice. --pager is a
better solution IMO.

This is bad. I was under the impression that this can be solved using
DARCS_PAGER (or PAGER), but if it affects other parts of darcs where a
pager is useful, then I will keep arguing for disabling automatic paging
and adding a --pager option that can support both use cases and would
make all camps happy.
