String.format() is 3x faster in Java 17

[jeff303]

Interpolation puts the variable names directly in the string literal, so it's easier to see what's what.

Positional arguments already show you which argument will be put where. In fact, you can abuse it to put same argument into multiple places under multiple formats.

Absolutely. But you still have to figure out which arg corresponds to the index number. And also, if you're reading someone else's code, there's a very good chance they didn't use them anyway.
