Could you describe the reasons why your setup is the way it is?

Personally, I've never used symlinks at this level, and if I did, I'm 
not sure I would see the problem with project-root returning different 
strings for those.

What exactly is the problem? Having the "same" project multiple times in 
project history?

I can name a couple of (probably minor) downsides:

* The project detection would be slower (more disk I/O).
* project-root would more often return a string that is not a parent 
directory of default-directory. Some code out there probably 
soft-depends on that.
