Discouraged in so far as that when an email solely references external
resources and doesn't bother to summarize or otherwise recap the
contents in the email proper; I'll ignore the whole thing.

Basically, if I have to click a link to figure out basic information of
a patch series, the whole thing is a fail and goes into the bit bucket.

That said; I have no objection against having links, as long as they're
not used to convey the primary information that _should_ be in the
cover letter and/or changelogs.
