 - The installation takes multiple manual steps that together can take about an hour depending on circumstances. We are working on improving this experience. See [Omnibus GitLab issue #2978](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/2978) for details.
 - Real-time updates of issues/merge requests (for example, via long polling) doesn't work on the **secondary** site.
-- [Selective synchronization](replication/configuration.md#selective-synchronization) applies only to files and repositories. Other datasets are replicated to the **secondary** site in full, making it inappropriate for use as an access control mechanism.
-- Object pools for forked project deduplication work only on the **primary** site, and are duplicated on the **secondary** site.
 - GitLab Runners cannot register with a **secondary** site. Support for this is [planned for the future](https://gitlab.com/gitlab-org/gitlab/-/issues/3294).
-- Configuring Geo **secondary** sites to [use high-availability configurations of PostgreSQL](https://gitlab.com/groups/gitlab-org/-/epics/2536) is currently in **alpha** support.
-- [Selective synchronization](replication/configuration.md#selective-synchronization) only limits what repositories are replicated. The entire PostgreSQL data is still replicated. Selective synchronization is not built to accommodate compliance / export control use cases.
