I've deployed a production instance of qpsmtpd 0.84-1 with the SPF plugin
taken from upstream git and libmail-spf 2.005-1.  No immediate trouble
observed, but I'll let it run a couple of days to see.

The upstream git SPF plugin and the one from the 0.84 release are
config-compatible, so this won't require patching of live configs.  There are
two config settings that will cease to have any effect (trusted forwarded
accreditation and best-guess processing, both nonstandard/legacy features
unsupported by Mail::SPF).  The existence of one of those two settings was
documented in Lenny's qpsmtpd, so this should also get a config update to
remove the mention of it.

Based on initial findings and assuming a problem-free test period, I'd support
shipping 0.84 with the backported plugin if the release team agrees.
