What do others do with DMARC? I'm inclined to just gradually turn up the SA
scores on SPF/DKIM failures instead, if only because
Mail::SpamAssassin::Plugin::DMARC isn't included in SA by default - and
presumably for a reason.
So far I only reject based on SPF.
I was thinking about rejecting DMARC failures with policy reject, but not
yet.

I don't check neither SPF, DKIM nor DMARC on incoming mail and don't plan
to. I use it only for outgoing mail and only because Google (and perhaps
some other "big guys") de facto requires it.
I filter messages only based on RBLs, manual blocklists and content
filtering (SA + many custom rules). And as for the latter, the messages are
sent to spam folder, never rejected. Rejections are based only on first two.
Funny, since multiple people in the past recommended rejecting on
spamminess, not on the results of single DNSBL listing.
Of course, that's your policy.
