I can see the footguns, but I can also see the huge QoL improvement - no more std::enable_if spam to check if a class type has a member, if you can just check for them.
... at least I hope it would be less ugly than std::enable_if.
There's a pretty big difference though. To my understanding enable_if happens at compile time, while reflection typically happens at runtime. Using the latter would cause a pretty big performance impact over a (large) list of data.
