Granted, I'm a biased because of $dayjob, but in my view someone
handing me a bunch of CA certificates as part of an installation is by
definition taking on the role of a trusted CA source. I assume you
disagree -- the question is: If there's an incident due to outdated and
compromised root CA's, which view will the security community take --
yours or mine? (To be perfectly honest, I'm way too biased to be able
to answer it objectively, but I ask readers consider this perspective).

Everything you list here is essentially a sign of you wanting TNF to
be a trusted CA source, so you've made me very confused with regards to
what your objection was(?).
If you [as in TNF] are willing to set that up (a means to distribute
a CA bundle securely, vouch for it, and provide a mechanism for users to
keep it up-to-date and verify its correctness), I'd be very pleased
(This is something I've wanted for a long time). I'm just against the
idea of "let's ship a bundle of outdated certs, with no means of keeping
them up-to-date, just to shut programs up.", which was my interpretation
of the original suggestion. (Your reply made it clear that I hadn't
made that point sufficiently clear in my previous posts).
I like the direction you're taking this; please don't take my posts
