I don't actually remember that many dialogues the last time I installed windows. It would be pretty obnoxious if there was a dialogue for every bundled program or feature that nominally competes with others: browser, media player, text editor, shell, drawing app, firewall, anti-malware, app store, etc. There's probably a least a couple dozen programs in that category.

It's not really clear to me why a few of these application types (like browser and media player) have been singled out in the past, but others are given a pass.

As long as third party programs can be treated the same as first party ones once installed (e.g. default program preferences) I don't really see bundling as inherently anti-competitive.
