Comment (by pmclanahan):
Yeah. The real issue is figuring out how to allow it to calculate the same
hash for the modified contents of the file at app run time and not just at
collectstatic time. I could do it if I was only dealing with the manifest
storage since that should never need to recalculate the hash, just look it
up. But the caching backend may get a miss and need to calculate it again
from the content, and I think it'd be too slow to hash all the dependent
files, replace the file names, and hash the CSS at runtime. I can't think
of a persistent place to put this info.
How bad would it be to fix this only for {{{ManifestStaticFilesStorage}}}
along with some documentation explaining the problem and why the manifest
fixes it?
