Everyone says this without trying it. I wear my Apple Watch to sleep. In the morning I shower and charge it. It is fully charged and lasts till next morning.
No problems here either. Lately I just wear it in the shower and charge it for a while when I sit down at my desk to work. It charges fast enough and I don't miss out on any activity tracking while I'm typing away at my desk.
I plug my phone in to charge at the same time. It's really not a big deal.
The only time it might matter is if I was doing a weekend camping trip or something, at which point the connected features of the Apple watch are less useful and a minimalistic Garmin would make more sense.
You missed their meaning. They meant that taking your watch off overnight to charge it gets in the way of sleep tracking.
Edit: People aren't reading carefully. https://news.ycombinator.com/item?id=27321770 clearly means what I've stated and then the parent says that they must not have tried charging their watch at some other time.
