Small anecdote from history: Back in the days, the conservative Swiss looked down on those vowel shift hipsters in Germany and thought that the simple vowels where good enough as they were. So the Swiss-German spoken today is basically a pre-vowel-shift German, "Haus" [pron: house] vs "Huus" [pron: Hoose]. Mid/northern Germans find it super hard to understand Swiss-German (or mistake it with German spoken with a Swiss accent). Perhaps we start to see a similar shift happening in France where yougsters start to mix up vowels in everyday words.
