Typical users aren't compiling Wine themselves. Most packagers have debugging symbols in a separate package.
-O2 -g has been the default for a while, AFAICT, so debugging symbols are already the default, for self-compiled Wine.
A lot of people around me do compile Wine because distros are usually days, sometimes _weeks_ behind official wine releases.
Please, make it an option - I guess it's just a question of adding two or three lines of code into the configure script, something like
--disable-dwarf2-debug
