Not really: burstable (“t”) instances haven't been updated in years. The current generation (“t4g”) still use Graviton2 processors. I get the impression that they would vastly prefer cost-conscious users to use spot instances.

the -flex suffix variants seem to be the new spiritual successor to the t burstable class.

eg c7i-flex.large, etc.

Ah, thank you for pointing these out! I'd missed the introduction of “flex” instance types (apparently in May last year[0] – still long overdue relative to the introduction of T4g in September 2020[1]). Curious that so far, they all appear to be Intel-based (C7i, M7i, C8i, M8i, and R8i). M7i-flex instances also cost 45% more than the corresponding T4g instances. That's sort of understandable, as the generational improvements probably bring more than 45% better performance for most workloads, but it also makes them harder to justify for the sorts of long-running,-mostly-idle duties they're being touted for.
