Yeah, no surprise that you wouldn't notice it. If you're expecting them to deliver it tubeless, you'd need to be suspicious to look for something amiss. Not like they had Schraeder valves mounted.
Is it wise to carry a wrench for the valves on long rides? I plan to continue carrying a spare tube and patch kit and tire levers. Seems to me, if I had a really bad puncture that sealant won't fix, I would need to remove the tubeless valve in order to use a regular tube.
Yes. Some multi-tools may have a box wrench that will fit some nuts, and I've seen valve kits that are sold with their own wrenches built into valve caps, or big wingnut-style nuts, so you don't need another tool. I carry a minuscule Leatherman-style multi-tool (Gerber Dime) that should do the trick.
