Thankfully, it is easy to add support for it.

No, not at all.  The special environment may be set up for a single
client/terminal/whatever only, but I doubt the code switches frames
before it starts whatever subprocess it wants to start in the temporary
environment.

It is to enable separate environments in cases such as this:

xterm #1:
        $ export FOO=23
        $ emacsclient  // new X frame

xterm #2:
        $ export FOO=42
        $ emacsclient  // another one, on the same display

I find this nice, but others loathe it, so it probably isn't worth the
added complexity.  The issue is moot now anyway. :-)
