I don’t think most people including those from the area would even associate the name with French, so there isn’t the same intentionality. It’s the same with indigenous language-origin or Spanish-origin place names in the US/Canada, our place names in general that are often centuries old and conceptually separate from their origins, and feels quite distinct from intentionally trying to emulate a foreign language pronunciation for one language but butchering words in another language (not that that’s unique to the UK).
