I wasn’t talking about mutation rates. Influenza has mini-chromosomes which it can swap between strains, leading to more variants since they can swap those mini-chromosomes. SARS-CoV-2 has a single linear genome - only recombination on the RNA level or accumulation of mutation will allow for evolvability. Also, viruses massively differ in their own mutation rates. So, yes, true.
