Gate B9 tells travelling public
exactly where they need to go - towards B gates and once they are in B concourse, then to gate B9.
Terminal 5 Gate 9 necessitates figuring out a way to
show that in the first place - a
lot of display systems (BPs issued anywhere and everywhere in the world, printed paper BPs, app mobile BPs from any and all airlines, wallet mobile BPs) might not be set up to show "terminal X gate Y" and at best you end up with a confusing mark like T5G28
and it does not have a way to deal with KLM concourses (future BCD)
and it preserves the issue that this couples departure gate number to a check-in terminal, and we already have enough confusion with "I'm flying to non-Schengen but this says the flight departs from terminal 2F"
At best you can do Xnn but then how is gate 634 less confusing than gate E34 when you have arrived in C concourse at gate C48 or... what 5248?
I really don't get it, using letters to distinguish concourses is a gold standard used in many airports touted as great (or at least useful) for transfers, including the likes of Atlanta, Munich, Istanbul, Singapore. Why would CDG move
away from this concept?
