I was going to add the ability to embed Garmin Connect activities just like Strava activities and segments, but it turns out they put up a
$5000 paywall in front of their API back in Feb 2014

What a dumb move by a company that is clearly out of touch with reality - interconnection is not a feature, it's a requirement. The "modern" Connect UI is so far behind the competition, without 3rd party developers, it will just continue to slide into irrelevance. The only thing I use it for is auto-sync to Strava.
So, no Garmin activity embedding on Staminist any time soon, sorry.
