Enable optimized housekeeping by default
What does this MR do and why?
The feature flag has been enabled on Sass for a while #353607 (closed). Since we've simplified the UI for setting the housekeeping !106741 (merged), we can enable the feature flag by default to enable it for self-hosted applications. After that, we can continue cleaning up the deprecated code.
