We could add a 'extension' field to the container profiles...

... but it would stil be nice if there was a default choice done in order not
to force users to always write that.

  Not much we can do about that use-case (and the asf+wma => .wma cases). Those
would indeed have to be hardcoded.

  That's another reason why re-using the typefinders instead of (extending)
pbutils/description is a bad idea.

  We could add an additional field in the descriptions internal structure to
contain recommended extensions.
  In addition, we could have support for the variants of quicktime:
  variant=apple => .mov
  variant=3gpp => .3gp
  variant=iso => .mp4
