AFAICS devices these days seem to be using HID because it means they
can get away without requiring custom kernel-mode drivers on
Windows. This lets them avoid a huge support headache.
Of course if the device connects only to Linux and MacOSX then you
don't necessarily need a kernel-mode driver anyway so this necessity
goes away.

It's certainly not a trivial protocol in my experience.
HTH.
