Follow up tickets to create once we're done here:
# Make "-Dcassandra.reset_bootstrap_progress=true" clear existing bootstrap data as it would make this feature more reliable
# Something else to consider is what to do with "nodetool rebuild".  It also uses the data from the progress table.

> From the patch I'm working on:
> {code}
> # In certain environments, operators may want to disable resumable bootstrap in order to avoid potential correctness
> # violations or data loss scenarios. Largely this centers around nodes going down during bootstrap, tombstones being
> # written, and potential races with repair. By default we leave this on as it's been enabled for quite some time,
> # however the option to disable it is more palatable now that we have zero copy streaming as that greatly accelerates
> # bootstraps. This defaults to true.
> # resumable_bootstrap_enabled: true
> {code}
> Not really a great fit for guardrails as it's less a "feature to be toggled on and off" and more a subset of a specific feature that in certain circumstances can lead to issues.
