proper tail calls

Will proper tail calls be implicit in ES4 or will there be a need for
special syntax? I hope it is just a required optimization but then I
read this ticket

and it seems there is a suggestion that the spec will only require
proper tail calls with a "goto" statement. Is it not reasonable for
the spec to simply require implementations to have proper tail calls?
Is it not acceptable for the spec to require certain implementation
internal optimizations?
