Literally the next sentence:

This is going to add a feature to the language that is dependent
on a library feature. Even though the compiler creates and
verifies the format strings, it's going to have to re-parse the
format string at runtime anyways.
Implementing string interpolation will just grow the dependency
on printf/sprintf. Cause like I said, no other function really
actually implements that formatting scheme themselves. This
limits and over-complicates the code around it.
