528491 Hmm, I'm sure there is a better way and I've used it before, but one of the general methods to react to all sorts of changes on phabricator is to create a Herald rule.

There you can create a rule for object R2135 (i.e. the Nautilus repository) that notifies you on commits, with the trigger "Always" (or you could set it to only trigger when the message contains the string "Wayland", etc.) and the action of "Send email to <your-account>"
Not sure off-hand how restricted that functionality is for regular users.
