I assume these socket options would be applicable more for new type of
applications. But I don't see a problem in updating existing
application with new socket option and recompile them, if the
application wants to serve special cases. For example, it's not
surprizing that common network application be modified for running
on mobile devices.

Also, per-socket control is more desirable than just per-process
control, as one application may choose to set different source
address for different set of sockets.
=> what I propose is not pure per-process control, it is to put the
control in the context of processes. It gives immediatly a per-process
control but with a way to manage the context from applications, it gives
a per-socket control too.
I don't think threading (as you mentioned before) is a good
alternative to that.
=> first I didn't introduce threading in this discussion, second IMHO
you haven't understand my answer about how to implement though-the-context
control with threads.

I am not sure I understand your point here.
=> easy, if you have in each prefix a public address and some temporary
addresses the flags don't affect the source prefix choice.
