Why do we still not have a function to undo resteems?

As a curator for @curangel I browse a lot of posts everyday. Most of them from my phone. Today I accidentally resteemed something for the first time, and I couldn't believe that it's still not possible to undo that. People have been asking for that option since resteems have been added to steem.

Please, can some developer take a few hours to add this?
Me and a lot of others who made the same mistake would appreciate it a lot!

Thank you.
