OneDrive for business Path+File Name character limitation is misleading

I don’t understand why Microsoft would publish a document on limitation like this?

The Document “Restrictions and limitations when you sync files and folders Applies to: OneDrive for Business SharePoint Online” https://support.microsoft.com/en-us/help/3125202/restrictions-and-limitations-when-you-sync-files-and-folders

States,  “In SharePoint Online, file name paths can have up to 400 characters. The limit may be less than 400 characters in some scenarios, especially if you have a very long URL path for the library.”

But it fails to state that the Microsoft Office Desktop Applications have different lower limits that are incompatible and present various unclear error messages when you try to open the files with the desktop application.

Also document should state the Microsoft Office Desktop application have different limitations.

Excel 2016 has a 218-character limit

Word, PowerPoint and Access 2016 are 259-character limit

Also Windows File explorer has a limited to 260-characters limit.

Now there is a GPO setting that enables long file name support but it doesn’t always work.

This document  “Restrictions and limitations when you sync files and folders Applies to: OneDrive for Business SharePoint Online” should include these other limitation, otherwise it's false advertising and very time consuming trying to get to the bottom of the unhelpful error messages.
