Two reasons:
1) Most native Windows apps don't read from or write to the invoking shell window
- it doesn't add much value to run them in the "foreground".
2) Once started (in the foreground) it's not possible to suspend such a
program.

Yes, but the key difference is that on Linux you can always get back to the
shell window by suspending the GUI app with ^Z (or whatever is your susp char).

The problem is that I often don't want to have to terminate the GUI app just to
get my shell prompt back.
