If you don't get any pure LCS solutions you could use an extension. macOS
has an API for this:

https://developer.apple.com/documentation/appkit/nsworkspace/1529991-isfilepackageatpath?language=objc

I just tested it in my macOS test bed for extensions and it seems to work.
It is the NSWorkspaceIsFilePackageAtPath() handler in this file:
