What should be necessary?

I don't think, that bug #420795 is a reason to not recommend
chemical-mime-data. Unfortunately chemical/* is not registered, but
widely used. So we have to live with the warnings (and at least I can
live with them). You will receive exactly the same warnings by adding
chemical/* MIME types to "your" packages. So what? I would suggest or
recommend chemical-mime-data. It also contains (as of version 0.1.95
IIRC) detection routines for KDE3 and libmagic/mod_mime_magic.

That is a really bad alternative. (a) You would create a conflict with
chemical/x-pdb for exactly the same file format and thus
shared-mime-info would need to conflict with chemical-mime-data. (b)
Most servers I know send .pdb files as chemical/x-pdb and not text/x-pdb
(note, that chemical/x-pdb belongs to the original RFC by Rzepa,
Murray-Rust and Whitaker more then 10 years ago). This will also be the
case for users using chemical-mime-data: detection routines will detect
attachments to be of type chemical/x-pdb when sending an eMail.
No, here I really recommend to stay with the historic name. I told you
to not *create* new chemical/* MIME types (exception may be possible for
"real" chemical file types, that are not application specific), not to
rename existing ones. The latter will only create more confusion.
