All of those are costs are at least as high for non-hybrid. The spec and API are just as easy to design (because we have really good and simple ECC libraries),

All of those are costs are at least as high for non-hybrid. The spec and API are just as easy to design (because we have really good and simple ECC libraries), and the bikeshedding and bickering will be a lot less if people stop trying to force pure PQC algorithms that lots of people see as incredibly risky for incredibly little benefit.
