I've seen landings (for non-security bugs) that involved up to 100
patches on one bug... or even more. While that's probably never
happened for a sec bug, multiple patches is not unusual (and in fact
common where there's a test added).

In fact it's quite common for people who are cc'd other than the patch
writer and reviewer(s) to look at the bug and comment on it, or to
submit an alternate or modified version of a patch previously uploaded.
And as Dan points out, frequently the reporter (when an external
'researcher') will weigh in on the patches being posted or use them to
verify if they fix the problem they found (since many times only they
can reliably reproduce the problem - private test setups, drivers, HW, etc).

Bite the bullet and at least make all CC'd people able to see all
patches, always. It's needed.
Another aspect of all this that needs to be thought out and verified is
what happens when a non-sec bug becomes a sec bug (and vice-versa,
though I'm far less concerned about that). When a bug becomes a sec
bug, all patches associated with that bug must become confidential. And
when a bug moves to be open (not sec-restricted), the patches should
also become open.
