None of these French buildups or preparations actually amounted to much OTL, except to eventually expand the RN through captures at sea during yet another war.
The British were certainly not kicked around in India, ending the war even stronger than at the start with the Dutch losing most of what they had and the French only getting their territory back at the peace talks. That point, that British resources on the spot were now a match for anything France or Holland or both could send plus any native opposition, was crucial.
Holland wasn't a British ally in the Seven Years War either and it was clear to the British that any alliance with Prussia which meant enmity from France, Russia AND Austria was a liability after that war.
