As of June last year[1] the Go team have pretty much drawn a line under this issue, with a very small amount of wiggle room to possibly reopen it at some point:
"For the foreseeable future, the Go team will stop pursuing syntactic language changes for error handling. We will also close all open and incoming proposals that concern themselves primarily with the syntax of error handling, without further investigation.”
Personally I'm OK with this, I didn't see any of the (many) proposals as a definite improvement. They all had trade-offs.
