No, they are still needed for some systems. Think boot disks and other
space constrained places.

No. We currently have drivers in the tree that do different things, yet
bind to the same type of devices. Here's two pairs for example:
bluetooth.c and hci_usb.c
ir-usb.c and irda-usb.c
Should one of these pairs go away too? I don't think so. Each of them
fill a need for someone, just like the Boot protocol drivers do. It's
up to the user to be "smart" enough to not enable the incorrect one.
And it's up to us to document this to allow the user to make the correct
"smart" decision :)
I also remember some older USB keyboards that do not work with the full
HID driver, but works fine with the boot protocol drivers. I need to
try to dig that device up.
