Afaict it is rare for a photographic TIFF to contain more information 
than can be stored exactly in a PNG. PNG is a much saner format than 
TIFF for a project like commons.

What we do need though is the ability to choose thumbnail parameters 
other than size. e.g. have a png in storage but generate JPEG thumbnails 
from it.
