That was true when the static chain was restricted to trampolines.  Since Go 
has started using it for cross-translation-unit closures, that makes it part of 
the ABI.

I did raise this issue at the start of the year, when I submitted the patches. 
  At the time, folks seemed ok with the additional restriction.
