But who tuns a true multiuser system these days especially one where

 Even disregarding hobbyists, more than zero but I expect the number is
indeed rather small.
 There’s a few points here:
 * You can still set a root password and use ‘su’ on Ubuntu systems if
   that’s what you want. Canonical are not enforcing a policy here, just
   setting a default.
 * The ‘sudo instead of su’ model is common everwhere, not just Ubuntu; I
   expect the motivation for the default setup on Ubuntu is
   simplification, not any theories about who can remember how many
   passwords.
 * Trusting sudo to enforce the a tailored access model is somewhat
   optimistic given its CVE record, and the general record of the setuid
   model that underpins it.
 * By escaping the setuid model run0 may improve on this issue, though it
   brings other kinds of complexity with it; how it balances out is
   probably a question for a few years time.
 * In the single-user context, sudo effectively creates the model that
   your single user account has privileges equivalent to root, but that
   you must explicitly mark any privileged operation. The former is just
   acknowledging reality, the latter is a useful guard against accidents.
 

+1 to all of that.
I use sudo if its just one thing I need to do, but if its messing with config files and restarting daemons, I use su -
