Typo in Item Attribute - stuck with it?

Hey again,

I ran into another question I can’t solve, it seems. The title kinda says it all:

I got a typo in one of the article attributes to create variants with. Of course I only spotted it after my colleague created a ton of item variants based on all the available attributes (awesome function that, btw.).

Are we stuck with that typo for good now? I have found no way so far to change the name of the attribute. Luckily it’s still the test run and not the final production system, but still well worth to know, I think.
