Yes, it could be installed by default. A few megs of harddisk space 
is hardly an issue compared with having a handful of strange daemons
(hcid, stpd etc.) always running no matter if any Bluetooth devices
are actually available or not, is it?

Starting these services on demand is more efficient and simpler for
the user. Perhaps 1 % of all users will try to use the Bluetooth stuff.

This would require that hcid is compatible with that approach. That's
the issue here. :)

The hotplug may not be the only way to start hcid. Other services
may require it to start too, of course.

This kind of dependency needs to be tracked too.
