Ah, OK. Well, checking editor applications isn't that much of a chore, there aren't that many people asking about their status here every day and there are enough meta editors to check. (Only meta and catmod editors are able to check status for editor applications, so it's not a problem for other editors anyway.)
Implementing that kind of technical solution is something that would only benefit a few people (those who for some reason have to wait longer than usual to get an answer to their application). On the other hand, it would not benefit the directory, not harm it but not help it either -- and so I don't see the tech staff devoting time to that. Their time is severely limited as it is.
