Fair, but that means you have to bring a special purpose charger with you anytime you go somewhere for more than ~36 hours. For me, that's the bigger issue. If I could charge inductively on the back of my iPhone, for example, I wouldn't mind as much.
I hear you, personally grabbing the charger for overnight stays hasn't been a problem but there are a few compact/inexpensive third-party dongles that are like the official charging cable but without the cable[0]. They can be stay in a car, laptop bag, etc. and charge the watch from an iPhone or another usb-c power source.
Huh interesting, I guess that would help somewhat. But for me, I prefer to pretty much never have to worry about charging my watch.
As a kid, I had watches that didn't need new batteries for years. As an adult, I was willing to trade off some battery life (down to a week or so) in order to get notifications my wrist, music controls, and activity tracking.
Although I can see some benefit in being able to see my Uber status in real time, or other app-related functionality, I am not interested in charging a wearable every day or two. I don't want to have to worry about whether I'm "using my watch too much" to be able to make it through a short trip, or until the end of my second day.
I know some people have different preferences on this, but for me a watch should be something that doesn't require any maintenance for weeks at a time.
Samsung had this reverse charging from the phone but they also dropped that function with the watch 7 :(
Having said that I did use it but it was terribly slow and both the phone and watch heated up too much. And the positioning was very finicky. A whole charge would last 3-4 hours where the official charger is 30-40 minutes.
Power banks with watch charging also exist and cheap aftermarket charging pucks. Not as fast as the included one but not bad.
