This is really weird, but it looks like it's correct. Can you provide a bench results?
@mcollina This is a major for find-my-way.

Don't forget to set it true in the Fastify.

Ideally this option should be disabled in Fastify as well, but I don't know the best way to do it: leave the default false here and open issue/PR to update dependencies in Fastify, or make it true here and send PR to Fastify with the option disabled

I would leave the false here, because it's a correct behavior and we can release a new major of fmw at any moment. In current version of Fastify it should be set to true by default, because otherwise it's a breaking change.
About changing it to false in the fastify in a future release. It's better to open an issue about this in fastify, but IMHO it never would be set to true by defauld in the Fastify, because it will break too many apps. It just doesn't worth it even if it's true according to the spec.

If there is any perf difference (I doubt), you can move the useSemicolonDelimiteradditional check under the charCode checking if. That would remove it from a hot path.

This PR comes from the discussion in the issue (fastify/fastify#5050). I've added a new parameter that allows the
