Do you want to backport the slaveargs changes just backported to 3.5? Or there is no need?

I'm not interested to backport this change. While regrtest of 3.5 is old, regrtest of 2.7 is even older. Backporting regrtest enhancements is more and more complex :-/

If we want to get more new regrtest features, I would prefer to "simply" copy regrtest from master to other branches.
