That may be true, but as far as sound stage goes, I don't think all of
the results are in just yet, and it depends on how the subs are crossed
over into the mains.. Dolby tends to agree with you though in the design
of their AC-3 and other Dolby Stereo formats.

Records did have all bass run mono below about 200 Hz because of
tracking problems on records, bass hard to one channel is difficult to
track with most needles, so the RIAA standard was written that way. In
CDs, the industry has followed the older conventions of bass and bass
drum to the center (mono), While this doesn't HAVE to be true any
longer, it still seems reasonable to expect both channels to contribute
to the low end (or deligate it to subs).
