Indeed, soly from typo's perspective it's indeed not a problem.
However if typo3 does a file_exists(..) or other file operations that 
needs directory scanning it's
indeed a performance hit.

Sounds like a good idea,
however could that be a potentional performance hit when typo3 needs to 
generate images?
Would would you suggest for tuning the days setting?
