Both.

I am thinking about the users.  Do you really think someone who has
difficulty installing a new udev rule (probably a line or two of text
copied from a google search) or installing a new version of usb_modeswitch
(probably one or two commands to the distro package manager) will have an
easier time doing a custom kernel-compile and update?

Updates in userspace are universally easier; on users, on kernel deves, and
on distro devs.
