This legacy cross-realm bot hasn't been used in several years, as far as I know. If we wanted to re-introduce it, I'd want to implement it as an embedded bot using those common APIs, rather than the totally custom hacky code used for it that involves unnecessary queue workers and similar details. Backported to the 2.1.x branch.
