Time to compile is a hard to gauge metric. I’d rather just be transparent that the instance type has changed.
It’s presumably in a big standardized DC. They don’t have a continuum of instance configurations, they probably upgrade rarely and systematically. If they are mid upgrade just have 2 instance types available then sunset the older one. Since the upgraded instance is a new instance type it can have new (or same) pricing. In addition, they could publish benchmarks for each instance type if they want.
It is literally what we see with cloud providers having v1/v2/v3 names for some instance types.
