Are you suggesting that I should given cast-iron guarantees with my suggestions?
No. Did I ever say that? But, if you knew all this when writing your original reply:
When I made the original suggestion, I was aware that in some scenarios the potential to eliminate duplicate files was beneficial; and that in others it could be compensated for by the necessary re-mapping of links to files.

I was also aware that in some scenarios, eliminating the user name entirely might lead to even greater disk-space savings, provided the link re-mapping mechanism was sufficiently robust to compensate.

I was also aware that there could be some scenarios where hashing the contents alone would be insufficient.

The why keep you all that for yourself, and didn't mention it? That's a lot more than the average perlmonk would consider. If you indeed did realize that duplicate files hash to the same filename, why didn't you say so? Instead, you say that the chance of collisions is remote.
