It's not purely an "academic" horse if you practice in the oil patch.  Reservoir engineers want a system recognizable to them and don't really care about practical geodetic applications, ... just solutions to their own problems and UTM is the way they want to go.
You're not going to succeed in educating the entire world's Oil Patch industry.
There are practical applications to this even if a classical cartographer is ignorant of the reasons.
The horse ain't dead, just maybe the jockey.

Ahhh!  Sigh,  Deja vu all over again.  I thought we beat this dead horse and
Dosier several years ago.

It seems worthless to expand the longitudinal accuracy of the projection as
long as the scale error and usefulness also goes to hell at the same time. 
The useful range for the tmerc is in the immediate vicinity of the central
meridian so why bother worrying about extending computational accuracy in the
longitudinal direction?

Enough is enough.  Please.
