Prompted by T268946: Offboard Pablo-WMDE from WMF systems.
Proposal of configuration change for wikitech to prohibit users from creating new Developer accounts which end with the strings "(WMDE)" or "-WMDE".
There is no policy at the Wikimedia Foundation to require or even promote the idea of using an employer designation suffix on a Developer account. The SUL account agreement theoretically made some sense during the era of the 'staff' group, but it has never made sense for a Developer account. Developer accounts are in large part about attribution for technical contributions, and that attribution belongs to a human being irregardless of their current or former employers.
I propose that the "WMDE" suffix should be treated similarly and disallowed from use for newly created Developer accounts.
