Well, most distributions choose saner defaults. For instance, RHEL/CentOS/AmazonLinux use noop io-scheduler by default for SSD based machines.

Though, I get your point: for instance, the TCP keep-alive defaults aren't suitable for all kinds of workloads: https://docs.aws.amazon.com/redshift/latest/mgmt/connecting-...

I guess, that's why performance tuning is an art form as it is workload dependant: https://youtu.be/89fYOo1V2pA
