My understanding is static chain is sort of compiler internal implementation,
any register could be picked if that is not used for passing argument, so I
would also prefer keep that out psABI spec for now.

I think every port is using a call-clobbered register for the static chain, and
it is not part of the ABI.

> static chain parameters are only used in Go
This is a lie. They are used with both Ada and fortan a lot. Both heavily use
nested functions.

I don't see how this is an issue static chain is only used for nested functions
in gcc and always local functions (except maybe with LTO).
