France and Germany propose hybrid schemes as well:

The german position:

"The quantum-safe mechanisms recommended in this Technical Guideline are generally not yet trusted to the same extent as the established classical mechanisms, since they have not been as well studied with regard to side-channel resistance and implementation security. To ensure the long-term security of a key agreement, this Technical Guideline therefore recommends the use of a hybrid key agreement mechanism that combines a quantum-safe and a classical mechanism."

The french position, also quoting the German position:

"As outlined in the previous position paper [1], ANSSI still strongly emphasizes the necessity of hybridation1 wherever post-quantum mitigation is needed both in the short and medium term. Indeed, even if the post-quantum algorithms have gained a lot of attention, they are still not mature enough to solely ensure the security"
