I still have some doubts, but your answer clarifies things a bit already, many thanks!
True, but I met divers from other agencies trained with a "DIR" (I hate this word! ) ) mentality whose protocols are basically the same as GUE. In some cases, despite protocols are not similar at all (for instance, in the case of side-mount/rebreather divers), they are compatible. At least, this is my (limited) experience up to now...
Marking lines in my own personal way sounds horrific to me... I hope they manage in a way or another to have few/no accidents...
Anyway, from what you are saying, assuming an instructor from another agency decide to follow GUE protocols (which are not a secret), he is free to do it and there would be basically no difference with a GUE course, do I understand right?
When you get in the water with a certified TDI/IANTD/etc. cave diver, you have absolutely NO idea how they will manage every scenario without going through every possible one in the pre-dive. Which nobody does, and leads to serious confusion when coming to a navigation decision and everyone starts doing different things. Same with failures.
When you get in the water with a GUE trained diver, anywhere in the world, there is no need to have those discussions. You not only know the caliber of diver you are dealing with but also how they will manage issues as they arise.

Without going through all of the procedures one by one, a good example is the GUE SOPs. They exist, whereas other agencies don't really have anything like that. TDI standards say things like "respond to a failed regulator" or "demonstrate navigational techniques" and leaves it up to the instructor to make up whatever they think should work (and every instructor think their way is the best, of course), whereas GUE SOPs give you a step by step procedure for managing every type of failure. This keeps everyone in the team on the same page as failures arise in real life (because they do). Same goes with navigation, there are many TDI/IANTD/NSS-CDS instructors in Florida that insist on NOT marking navigation in any way. Then there is a group of instructors in Mexico that teach to jump off of a personal arrow, placing that arrow in the direction of YOUR exit even if it contradicts the system markers (horrible, horrible, horrible idea, by the way). You would think "an S-Drill is an S-Drill", "a valve drill is a valve drill" or "marking a piece of string is marking a piece of string", but it's not. There are many varieties to all of this stuff, some of it is very lazy or just plain dangerous.
