Should we identify ops with keybase too?

**I forbid you from merging this before at least one other person than me has appended their proof to this file!**

In case we decide to do that, I added my proof to this text file. Please
append yours there too.

I know that at least @foxiepaws has keybase account, but I don't know
about @Edelwin . @ProgVal wasn't interested earlier.
