Enabling the service for unstable/testing is not an option, as it might
cause regressions, which we don't want to risk this late in the release
cycle.
As for the version in expiremental: Upstream dropped the readahead
functionality in v217, so there is nothing to enable anymore:

I'm tagging the bug wontfix for now, but I'm inclined to just close,
since going forward, it probably doesn't make sense to keep it open.
