My understanding is that the data stored in reparse point is not intended for
end user (in this case, client system's Explorer) consumption, but solely
exists for the benefits of the host file system management driver.

The very presence of the reparse point attribute is all that client system
needs to know. The data stored in it is (supposedly) of little utility outside
the host filesystem.
