I think the biggest difference (judging from
https://wikitech.wikimedia.org/wiki/Nova_Resource:Bots, I
don't have an account on Bots) is that Tools is tool-cen-
tric, i. e. tools do not run under their maintainers' ac-
counts, etc.  That migration will involve some fiddling with
paths, usernames and hosts anyway, so I think it's much eas-
ier if not one project (and its admins and developers) has
to accommodate both.

As the number of bots on Bots seems to be limited and time
is not an issue here, I think just waiting a few months is
preferable.
