Thanks for the references. They happened before I subscribed to the dev list.
I just read through them here:

There was *no* objection to adding tested DNSBLs to existing releases. Except
for your claim, again, in the second thread, that there had been a previous
objection. Which there wasn't, in those threads. The only objection of any
kind was:

Which is not relevant to this bug. Also, I'm not convinced it's true.

And this is where you first claimed there had previously been a relevant

Was there another thread that I haven't read where this resentment was

"MSPIKE (previously named ANBREP) has proven consistently in weekly masschecks
since before the release of 3.3.0" - Warren. So MSPIKE has been good since
before 2010-01-27. Two years. And from what I can tell, for at least a year,
it hasn't been added to the default rule set because of your unsubstantiated
claim that somebody else objected.

Can you start over and tell me why you don't think MSPIKE should be added to
existing 3.3 releases? I don't think anybody will mind the increased network
load. I think everyone will appreciate the resulting increased accuracy.

I wouldn't care so much if it was easy for us to maintain two sets of rule
updates. But we can't. So not adding MSPIKE to 3.3 means never adding MSPIKE
to spamassassin, or at least sub-optimal scoring in one of the major releases,
which you don't seem okay with either. Which results in spamassassin being
incapable of ever adding another useful DNSBL, which is not okay.

Somewhat related, spamassassin needs an announcement list, for announcing
changes like this, and releases. (bug 6714)

Not relevant to this bug, bug I can't help repeating why we use reuse, from one
of those threads:
