This is prompted by https://discuss.python.org/t/vote-to-promote-itamar-oren/106078/
Apparently @itamaro is not a Core Developer, but he is in the @ committers group, which is named “Python Core Developers”.
When I saw the voting topic I thought I had misremembered him having the icon, but he is in this group and therefore has the icon on DPO.
I think this can also explain some of the people that thought he already had the bit.
Is there a way to distinguish these cases better?
Over the years, various terms have been used for (what I thought were) the same thing: commiters, core devs, core team, etc. Is there a difference between “commiters” and “core devs”?
I’d like to unify on “core team” as it’s more inclusive of all of the skills and activities involved.
I suspect this was a purely practical measure so Itamar could post in Committers about organising the Bellevue sprint (1, 2), to make sure the messages reached the core team.
The devguide’s team log is usually the best place to check.
Apologies if this caused any confusion!
@hugovk is correct in the original reasoning behind this, around the Bellevue core sprint. fwiw, I did change the “Title” in my profile to “Regular”, but perhaps it would have been better to remove me from that group after the sprint.
@itamaro I think the confusion mostly affected you and delayed you potentially getting the commit bit 
I mainly opened the issue to make people/moderators aware that this is a likely source of confusion. In the future, for temporary access like this I would probably create a new “Temporary access” group. Even if we changed the naming of the original group to help solve the confusion @nedbat pointed out I don’t think many users would understand that somebody in a group called “committers” or “core developers” is not a committer or core developer
