• No longer provide suffix vfs in the wizard/folder wizard
• No longer allow to switch to vfs in "..." menu
• Add warning that suffix vfs will be removed without a migration path in 7.0. Recommend to switch to native files.

"No longer provide suffix vfs in the wizard/folder wizard" -> Does it mean the virtual filesystem be no longer exist?

Does it mean the virtual filesystem be no longer exist?

vfs is a platform specific thing - there is already a platform specific implementation for windows. Mac vfs is planned for 7.1
Linux has no explicit plans yet.

in the scope of 6.0 the suffix vfs (platform independent) can still be used.

Given the intent to deprecate VFS suffix support prior to introducing Mac VFS support, please could you provide an option to allow users using this sync method to defer upgrading until VFS support ships?
