But in all seriousness the point is, Blizzard had to put in EXTRA work to disable them, so unless "disable covenants outside of Shadowlands" came up on the "Wheel of Tasks to Waste Time Since We Have Nothing Else to Work on for Shadowlands" that they spin every Wednesday, they have their reasons (maybe to stop the possibility of "Rexxtroy" situations with weird covenant ability interactions in the old world?)
It's old content, you don't need your covenant ability.
