Do I understand correctly that you want:

1. one derived identifier to be used to cast the vote and stored without
association to developer,

2. another derived identifier to be used to confirm the vote, and stored
with association to developer?

I suppose this could work.  However, it would weaken the privacy
protection much.  Any active watcher (say, Infra or election official)
would be able to notice simultaneous appearance of the vote
and the voter entry.  Sure, they could also break the system by hacking
the scripts over or adding voters manually rather via the script
but the whole point is to limit privacy exposure to the minimum.

Furthermore, I believe the fact whether one has voted or not is also
a matter of privacy.  Expecting people to explicitly indicate this is
violating it, so it doesn't seem the correct solution to the problem
at hand.

Maybe Trustees should consider finding a better way of determining when
to retire inactive members?  The simplest solution that comes to my head
is finally requiring all Foundation members to be active developers, or
at least setting same rules for both groups (i.e. retiring Foundation
members when they stop making new contributions to Gentoo).  Given that
there are only a few Foundation members who are not devs, either way
shouldn't be a real issue.
