Is this code already able to handle correct order of parameters ?
I.e. is this code parameter order independent ?

I can make add a copy of older pass1_rse and pass1_sort to the server.
But this code is not very static and changes often. My experience tells
me it means that non-default variant will die soon.
What about introducing correct behavior in Alpha 5 and if there will
be many complaints add bug-emulation layer ?
I think it is really difficult to say now how many applications
strongly depend on older buggy behavior. Public testing will tell
exactly that.
