The core standard (defining the communication layers) is actually
not too bad, compared to some I've had to look at.  It's huge, but
a lot of it is describing low-level radio stuff (below the hci layer)
which your bluetooth chip takes care of.

All the "profiles" (application layers) have their own separate
standards documents, and there indeed is a morass of (non)design
by committee.

Maybe I was lucky, but my random choice of development hardware
(a cheap generic usb dongle with a CSR chip) has seemed to behave
just as the spec says.  Of course there have been surprises, but
so far these have been where the spec was ambiguous and my guess
didn't match the firmware designer's guess.
