Yes, as a Spaniard who has been exposed to AZERTY in the past, I simply cannot understand the logic behind giving é, è, à, ç, and ù such arbitrary individual key allocations, which then make them explicitly untypeable as uppercase letters using the Shift (= "Majuscule") key... which as a result is required to type digits (majuscule‽). However, somehow the diaeresis ¨ and circumflex ^ diacritics deserve their own deadkey to be able to type ê and ï. I see this "improved" AZERTY leaves most of these issues untouched. Meanwhile, in a Spanish QWERTY, reinforced by its requirement to support Catalan and Galician, ç and ñ have their own keys which can be uppercased as normal, and the acute `, grave ´, circumflex ^, and diaeresis ¨ all have their own deadkeys which can be used with any vowel character, uppercase or not.
