With it's pros being the ability to know how close the points are just having the 2 coordinates and arbitrary precision.

Who knows how far away epic.region.music and epic.global.music are from just the names? While 18SUJ2163104440 and 12SVC0452723150 are 6 grid zones apart east to west.

That's a handy property for the 3 people on Earth who have the algorithm behind it memorized, but the rest of the world would prefer to be able to easily read, write and share the codes.
The algorithm is absolutely trivial -> https://en.wikipedia.org/wiki/Military_Grid_Reference_System

It's actually quite pleasant to use and allows you to just truncate to the level of precision you want. S/He just posted the 1m resolution string when 18-SU-J-216-044 would get you to 100m.

All this said, I think the real issue is that we refuse to PICK a standard and so every device with a GPS and ever map has one or two of

-MGRS

-UTM (almost identical to MGRS)

-LL DD MM' SS.ss"

-LL DD.dddd...

-LL DD MM.mmmm...'

etc.

If you make a device that can output or accept a location string, make sure it can handle all LL cases and UTM/MGRS.

I think we have different definitions of trivial. Or you put a lot of trust in the average persons intelligence or more importantly laziness.
Most people can tell proximity in lat/lon coordinates based on the algorithm they learned in first grade: the number line. Perhaps they could use a similarly ubiquitous system, like the alphabet. There’s even a song to help you memorize it!
