Thank you for catching my oversight!!

I dug a little deeper and discovered that the popular NPM packages that
make use of jshttp/mime-db rank the source of each MIME type and discard
duplicates which have lower "preference".  For example, the
jshttp/mime-types utility does this:

  // source preference (least -> most)
  var preference = ['nginx', 'apache', undefined, 'iana']

and then discards duplicate mappings which are of lower preference.

https://github.com/jshttp/mime-types/blob/eca390b71004a70f4551197638c077cdba8cf954/index.js#L155

I think https://github.com/broofa/mime does something similar.

The result is that the two popular NPM utilities for getting a MIME type
from a file extension (see <https://www.npmjs.com/search?q=mime>) ignore
the ".org" -> "text/x-org" mapping in favor of ".org" ->
"application/vnd.lotus-organizer".

Shall we consider this this after we find a way for these low-preference
mappings to be useful?

I agree that it would be good to track this information in one place so
we don't repeat ourselves ;)

Thanks,
