It would be better (IMHO) to accept a file name (in taint mode) and sanitize it within your module.
The intent was to reinforce that incoming information (in this case a file handle with no other attached information) should be sanitized within your module.
While the source could well be benign, it is not that hard to use secure practices from the start.
Given that my background is information and systems security, I tend to preach security best practices (in conjunction with PBP ;-), of course).
