I understand your position, but there are some another problems
with this approach.  In real world, you can't predict for all
cases whether your outgoing leg will pass the same servers as
incoming leg. If you maintain code of border system (e.g. between
Internet and local network) and it's improbable that this code
will be used for other setup style, you can do this. But in
general it's quite danger. I don't suppose you're writing stack
for such local task; likely it's universal one. If so, better
create new tag and avoid any chance for having identical leg ID.
