Sorry about bugging the list about it, but can anyone please explain the reason for not enabling the Interlanguage extension?

See bug 15607 - https://bugzilla.wikimedia.org/show_bug.cgi?id=15607

I believe that enabling it will be very beneficial for many projects and many people expressed their support of it. I am not saying that there are no reasons to not enable it; maybe there is a good reason, but i don't understand it. I also understand that there are many other unsolved bugs, but this one seems to have a ready and rather simple solution.

I am only sending it to raise the problem. If you know the answer, you may comment at the bug page.

Thanks in advance.
