·First time I hear mainspring should be replaced at every service. I don't think I agree... unless service is done once every twenty years or so.
Can an old mainspring be the main reason for low power reserve in automatics?

It’s common practice. Done by every watch brand service centre on the planet, and by most watchmakers I know...of course there are those who don’t, but in my view they would be in the minority...
