It's just a matter if Trino manages this data or external system. In general, I see this feature as an "escape hatch" for cases when we don't directly support a standard property, or there the user has a custom property in their environment, but I want to encourage the use of the Presto property system because it is safer for end users to use due to the type safety of the syntax and the property specific validation code we have in some cases. corresponding to the snapshots performed in the log of the Iceberg table. extended_statistics_enabled session property.
