Apparently the idea to rename the Priority field value from "Lowest" in Bugzilla to "Needs Volunteer" in Phabricator created more confusion than expected. I am sorry for that - wasn't intended.
To fix that, there are two questions that welcome input in https://phabricator.wikimedia.org/T78617 :
1) Our Phabricator currently offers six levels of prioritization. See https://www.mediawiki.org/wiki/Phabricator/Project_management#Priority_level... Do project maintainers / devs really feel a need for planning to differentiate between "low" priority and one level below that? Or could we reduce our six levels with five levels?
2) If there is a need for a level below "low": Let's rename "Needs Volunteer" back to "Lowest" (Looking at the proposed names in T78617, "Lowest" seems to be the least confusing term / smallest evil.)
If you feel like helping make a decision by adding some *additional* arguments based on your experience, please raise your voice in T78617 after reading the existing comments and arguments in that task.
Thank you for your help! andre
