For companies using Google Calendar as the primary meeting scheduler, one issue with this is that there's a setting for short meetings, but it only supports ending the official meeting 5 or 10 minutes early: "End 30 minute meetings 5 minutes early and longer meetings 10 minutes early".
But if you're in a meeting already, people are expecting that they have time until the hour or half hour point, so in spite of the meeting officially ending at H:25, it really almost always lasts until H:30 unless you have someone who wants to leave early and can enforce it by actually leaving.
It surprises me a bit that even engineering managers at Google agree with this policy and yet it's not an option in the Google Calendar settings.
