tried it and it allows me to revert daddykotex/smithy4s-code-generation#13 successfully
I'll do further testing with regards to the different internal implementation we have to make sure everything still works there as well, then I'll mark as ready to be merged

tbh I wouldn't revert it fully, removing CORS is a security improvement :) but if you mean the resetBaseUri part, absolutely let's kill it.

yeah, no need to reintroduce cors in that case so I just want to remove the resetBaseUri middleware
