Okay, I made another patch,
That adds some deprecation warnings to many of the functions/methods
in the module.
(I think the 'strict' parameters should also be deprecated. But I'm
considering actually making a new class, MimeTypesRegistry, or
something, and then just making its API stay mostly compatible with
MimeTypes, but extended to behave the way I think it should, and
deprecating the MimeTypes class altogether, making it a subclass in
Is there any way to explicitly (i.e. in code rather than docs)
deprecate string flags or dicts/lists from the module global
namespace? I don't think users should be mucking with the module's
singleton at all, and should be forced to make a new registry instance
to customize the behavior, so they don't break each-other's code.
