Due to lack of ability to find an invested maintainer and inability to find time to do routine maintenance and community building, this package is no longer maintained. Please see the discussion ? Maintainer help wanted for more information.
If you need it, yes. Normalizr is and has been at a stable release for a very long time, used by thousands of others without issue.
Fork Normalizr on Github and maintain a version yourself.
There are no current plans to resurrect this origin of Normalizr. If a forked version becomes sufficiently maintained and popular, please reach out about merging the fork and changing maintainers.
