So this is less about this package itself but rather this general issue
of parsing Content-Type headers, which has come up repeatedly...

"Be conservative in what you do, be liberal in what you accept from
others"... when it comes to the web, we should follow the Robustness
Principle:

It's absolutely true that Guile should enforce producing correct HTTP
requests and responses.  But as much as it's irritating as schemers,
probably the ultimate group of "do the right thing" if there ever was
one in the programming world, if we cut off sites that do the
slightly-wrong thing, we're cutting a lot of potential users from a lot
of the web... making Guile a lot less attractive of a language for
scraping, etc...

We should at least provide some sort of option to permit fuzziness, or
to convert incoming http requests to fill in some default value, or etc?
