Interesting. So fixed ratios in gearbox but presumably sprocket changes are allowed? Takes out a lot of mechanical expense. Savings may be eaten up by modelling/analysis to pick the best ratios for the season.

For tracks that the teams have experience with, they already know optimum gear selection for every corner.

It's not time consuming to change but designing/making a dozen cassettes with different ratios (plus spares) adds a lot of expense.
 
For sure, but unless the rule were written that the internal ratios all have to remain stock, that expense is still going to be there.

For the teams that also race in WorldSBK, that money is going to be spent anyhow.
