Inaccurate XML Import documentation and text on Confluence Admin>>Backup and restore

Our documentation says to check your instance to see whether it is compatible with a particular version of XML backup.
The documentation says:

You may not be able to import spaces into earlier versions of Confluence, the Backup and Restore page in the later Confluence version will give you some indication of whether it is likely to be compatible.

So the doc sends you to the backup and Restore page, which reads, in Confluence 5.10.1:

This site accepts full site imports from Confluence 4.0 and later, and space imports from Confluence 5.3 and later.

In fact, imports across major versions fail, and imports from Cloud fail except on the latest version.

The Cloud Backup Administration page is also inaccurate:

Going to an Self-Hosted Instance
You can export and then import your data into a Self-Hosted Confluence instance. Currently, Confluence 5.3 and newer versions are able to import OnDemand backups.

In fact, the restore from Cloud to standalone will fail unless your server instance is on the latest version

The quote following is displayed on the Export XML Options page. It explains that any space backup generated from Confluence Cloud can be imported into any Confluence standalone/self-hosted versions between the latest version and 5.3. In fact, Space backup import will fail with errors on Confluence versions prior to 5.7.

Export the space to a zipped XML file. You can import the XML file into earlier Confluence versions from 5.3 to 5.9.0-OD-59-126, and into compatible later versions.

Please let's provide accurate information in our docs and on the instances' admin pages.
