This option shouldn't be removed, since it has a significant and well-defined functionality, which doesn't hurt anyone and is useful to a few people.

When i replied about it on wikitech-l, i knew one university professor that used it. Since then i found one more such person.

In fact, you can just check how many people actually use it (in each of the 800+ projects). If it's more than zero, keep it.
