I once had a conversation with a very good developer who said, and I quote, "calendars are solved". But no, calendars are not solved - I still can't share calendar data from home and work to have a single seamless calendar, and the same sort of problem afflicts anyone working in closed proprietary systems like institutional LMSs. Against this background, being able to share calendar data between two closed proprietary systems is a big deal. But what we want and need is a way to access our own calendar data without having to be inside some closed system. This is actually a hard problem, because these systems usually deal with sensitive and proprietary data. But 'Canvas, and TimelyMD share data' isn't the way to deal with it (especially in a privatized health care sector that has incentives to monetize personal data, as in the U.S.).
