Turn off Code Signing trust bit for all included root certs

This hasn't yet been done, but ISTM that there's no reason not to do it now.  https://email@example.com/msg02409.html
Assuming I've parsed certdata.txt correctly, there are 2 built-in root certs that should be removed since they're only enabled for CKA_TRUST_CODE_SIGNING: ComSign Secured CA https://crt.sh/?id=25533 UTN-USERFirst-Object https://crt.sh/?id=17811155
Thanks for the reminder. I filed Bug #1366403 and Bug #1366412 to remove those root certs. Is there anything else we need to track in this bug?
Kathleen: If you're good with the removal, then the next step is to remove the CKA_TRUST_CODE_SIGNING attribute from all the roots. Rob's just pointed out the ones that are _only_ trusted for code signing :)
Kai and Keeler, We can do the following with this bug: 1) Turn off the Code Signing trust bit for all root certs or 2) Remove CKA_TRUST_CODE_SIGNING altogether. I think you developers will have better insight into the best approach here.
I'm assuming NSS as a project would still want to support clients marking their own roots as trusted for code signing, so I believe option 1 (just turning off the trust bit) would be best here.
Sounds good. Updating title, and I will add this to my list for the July batch of root changes. Thanks!
