Fat chance that this long overdue safety initiative will ever get traction!
Dream on, whatever next? The Yanks using correct ICAO R/T phraseology, discipline and order within Spanish ATC, cheap fuel in Italy, ramp agents in Brazil that you can trust, CAKOK in Beijing?
I guess you´re right !
More on a serious note, I honestly think that it will take quite some time for Spanish pilots/atc to understand each other when both are speaking English, unfortunately. Although this would help other pilots, monitoring the same freq, that don´t speak, neither understand Spanish. I imagine some pilots probably get a bit 'lost' traffic wise when approaching Spanish airports.
As for Franch, like it has been said, I reckon they wouldn´t take this so easily.
