Do you use this somewhere in the runtime?

Exactly, was trying to use it in runtime because somehow the main runtime only cares about the extrinsic blob. Eventually, we would get rid of the approach loading the full opaque extrinsic, but it can still be nice to have this derive anyway if that doesn't hurt.

@bkchr Will do, I thought it's a mere fairly trivial change and made a really quick PR :(.

Bot will approve on the behalf of @bkchr, since they are a team lead, in an attempt to reach the minimum approval count

I know, but I'm still interested on a why. Otherwise I will need to ask again and wait and bla. Could be faster :)
