So, Chrome supports only pure MLKEM1024, while it supports the hybrid version with MLKEM768?

Is that because you believe pure MLKEM768 to be too vulnerable and needs beefing up with X25519?
Or is it a computational load issue with the hybrid being about twice as expensive as MLKEM768 alone,
so with the pure mode you can afford the larger size which increases the load by about 50%?
