Well, the problem I see is imposing fundamental design decisions
caused by corner cases (file name limitations on certain platforms).
Imho the most portable designs I came across so far where those that
do not attempt any platform-specific treatments.

The territory to deal with such mappings is full of pitfalls, as I
said earlier, I wouldn't do that for simplicity reasons. Less is more.
