Due to problems described in T241691, our community decided that we need to have a user group with the "pagequality-admin" right.
Without this right some deleted pages cannot be undeleted. And as discussed earlier in T167491 no user should be assingned to this group permanently.

A recent discussion:
https://pl.wikisource.org/wiki/Wikiźródła:Skryptorium/Pulpit_techniczny#Nowa_grupa_uprawnień_do_celów_technicznych
shows that there is clear consensus that we need such a group and that admins should be able to grant this right to themselves.

The suggested Polish name for this group is "Administrator statusu korekty" (plural: "Administratorzy statusu korekty").

I suppose, that a similar user group may be requested by other Wikisource communities in future.
