210.6(A)(2) is unenforcible, though, as there is no restriction on cord & plug after it's installed. You can install it with the intent of using a 1500VA UPS or a 2500Watt tea pot, but as you won't be putting it in, you can't know whether he'll come back with a 700VA UPS or just plug a 60W luminaire straight into the wall, violating both 210.6(A)(1) and 210.6(A)(2). Regardless, the installation is perfectly safe.
I mean, it's impractical to retrofit new circuits after the drywall is up, so how many new homes are built with 240V welding/tool outlets in the garage/shop "just in case" before the homes are even sold? (OK, probably a small %, but I'm sure there are still quite a few. I did this in my house at least.)
240V coffee pot outlets in the kitchen should be mandatory
