what's the plan about ext_storage_proof_size_storage_proof_size_version_1?

AcalaNetwork/chopsticks#754

not sure if there is already an issue about it but looks like more teams are using this feature

Well, I was vehemently against RFC 43.

In the discussion, I explained that in my opinion this function isn't implementable because generating a proof is currently an implementation detail. @bkchr and @skunert on the other hand claim that they could properly write a spec of how proof generation works should work deterministically. If such a spec appears, I can implement it, otherwise I won't.

You can just provide the host function and return 0.

I went with the solution of tossing the hot potato to the API user.
