With any reasonably modern phone, wouldn't this problem only apply to
areas where GPS isn't available (e.g. basements) and the system tries to
fall back to using tower triangulation?

AIUI, part of the registration process's purpose is to give a default
location for your new "tower" so that emergency responders at least know
where to start looking if no better location information is available,
e.g. because the caller can't speak or is disoriented.
