I absolutely agree with your wish that this information should be 
available without any hacking but I think that there is no way to load a 
file with Get which is not the first  in FileNames[filename,$Path] 
unless you use an absolute path for filename. The latter is easy to 
handle and covered with the else condition in:


so I think the above construct should work for the case you named.

I'm sure you have seen the post of Carl Woll about an undocumented 
private variable that holds that information. Looks like the people at 
Wolfram found this information valuable, too, so it probably is only a 
small effort to provide that information to the users/package developers 
without hacks and workarounds.

Sorry for the post with only marginal new information but maybe keeping 
the thread alive convinces someone that we really want that little 
information accessible :-)
