The "Lisp debugger" may be referring to `debug', not `edebug'. See bug
#3466 - "have `d' in debugger treat macro expansion like `c' does".
That said, I think prog2 is rare enough (a quick M-x rgrep over Emacs'
lisp code found only 66 matches vs 874 for prog1 and 8585 for progn)
that it wouldn't really matter that much.
