Not as I know of. I have only encountered it when going through Linux 
 From Scratch
(https://linuxfromscratch.org/) and when building custom embedded 
systems.
There are a couple of programs like parser generators that basically 
depend on
en_US.utf-8; for example, some test routines check the output of 
time-related
functions and may expect the US format in their tests.

I can't say why this appear now, as I have used en_US.utf-8 as a default 
for years now.

(Some of my colleagues use de_DE.utf-8 though.)
