I consider that a valid tradeoff, with the breakeven point to be
determined by the moderators/list owners/site owners.

OK, I'm happy again, no crazy people here. :-)

But IMO the pipeline architecture already does that.  I haven't looked
closely at the Mailman 3 webserver, but my understanding is that it
gets a pipeline too.  It seems to me that once you have that (and IMHO
that is extremely desirable just by analogy to the list processing
pipeline, which I have written several Handlers for), the rest is
going to be pretty CAPTCHA-specific, and quite possibly specific to
the particular CAPTCHA implementation.

It might be worth recommending a third-party implementation of a
best-of-breed (reCAPTCHA?) plugin or even providing one ourselves, but
I plan to leave that decision to Barry, as long as the documentation
for any such feature points out the limitations of the technology.

Don't be.  It was a $150 bike, and the Minister of Finance in my house
approved purchase of a $670 replacement. :-)  All I really lost was a
junk lock and about $50 resale value.
