Exactly! I have never in my life heard anyone complain in person about the iPad wall charger, and that's the exact same "problem" as in there. And the iPad is infinitely more popular than the Switch. But GAF has to find something to complain about at every moment.
I have no issue with it, but to play Devil's advocate...
Most people aren't doing intensive gaming on their iPads, and from the first model on they tend to get right around 10 hours of battery life for all other uses. So the brick is a bit moot as people rarely have a need to charge it other than at home at night (or hotel room when traveling).
That said, again, nonissue. Buy an extension cord to fit it in your powerstrip if needed (which is what I'm doing as above), a good battery pack is a better option for charging on the go, with the brick left at home or in the suitcase/hotel room when traveling.
The only real valid concern is how much power you need to charge while playing--that could limit which battery packs provide enough, which car chargers, whether you can keep a charge using airplane USB ports etc.
