Chamonix bars/restaurants and new Covid 'pass vaccinal' rules

This is the best synopsis of the rules I've seen so far.

"if you want to access the likes of restaurants and museums, you'll need to have a 'pass vaccinal', which comes with its own set of requirements.
To enter France you'll need to be fully vaccinated, aka have received a full course of an approved vaccine, at least 14 days before arrival in France. Under the country's new booster rule, if your vaccination was completed over 270 days ago (approximately nine months), you'll need to have a booster jab to be considered as fully vaccinated.

As for when in France, currently anyone aged 16 or over requires a pass vaccinal to access venues such as restaurants, bars, museums and sport venues and ski lifts.

To obtain this, you need to be able to show proof of full vaccination, proof of Covid recovery, or a medical exemption from vaccines.

If you want to use proof of vaccination, you need to have a booster jab if your vaccination course was completed over four months ago based on when you're in France.

So essentially, if you want to visit France for a holiday and your vaccinations were completed over four months ago, you're going to be required to have a booster jab so that you can obtain a pass vaccinal."

Has anyone been to Chamonix recently that can comment on whether this requirement is being actively enforced at restaurants/bars? We're a mixed group, all of us have had 2 vaccinations but come in at over 4 months ago and have had friends who have had the booster and it has really knocked them backwards. Some are a bit older and weren't planning on having the booster until a bit more info came out about it so they're not conspiracy nutters!

Any info would be greatly appreciated.
