Functioning as it should is good.

The thing to consider here is, do you consider yourself an average user? Most of us here would not care if they didn't have firefox or chrome as their default browser, to myself it's practically meaningless apart from win98 days setting some near useless lump as the default to catch auto activating BS, but to ordinary folk they can get weird ideas they have to use it ... IIRC M$ went to a little bit of trouble to stop people easily making firefox the default browser, and some internal links are edge only without a really good work around. I don't see them going to all that trouble unless there's a slight benefit.
