This affects group (team) permissions as well - having to add a new team to multiple repos with specific permissions is a manual slog and hard to audit. Even the expanded permission categories are frequently inadequate - there's no CI focused "Let these users write to the repo and change hooks" permission level - all CI systems that self-manage hooks need full Admin rights.
The other code hosting I actively use is Gerrit, and the ability to hierarchically control what groups have specific permissions on multiple repos is far simpler and easier to use, from an admin perspective.
