People adopt the communication style of others. If the “quick call?” method is common, it means that many of its users don’t want their communications logged, meaning they commonly ask for sketchy stuff. Act accordingly; i.e. always send a follow-up email summarizing what they asked you to do, and give them the opportunity to change their tune.

In my experience, the reason for most "quick calls" isn't quite this nefarious. It's usually just about making a request for which the asker wants immediate confirmation of handoff, and/or for which they haven't done much thinking or built a good justification, and they are proficient at controlling synchronous conversations to avoid questions and clarifications while still getting to yes.

Agreed. I've seen multiple large enterprises where messaging was common (perhaps with a bit more emphasis on emails than normal) and calls were not. It's not an inevitable consequence of scale.
