Just another hack for a very old version of connector.  Don't use it.
It doesn't do anything anymore anyway.

Connector used to add 'mail' folders to the shell's tree directly, and
then the mailer would be told to open them directly from resource url's.
That went out after and including 2.0.

Most of camel-provider is used to drive the interface - in version 1.0.
It is very archaic, just copy one that looks about right (e.g. imap
probably) and ask questions if you can't work it out.

Hidden is therefore a ui context ...

As to your last question:

#define CAMEL_PROVIDER_ALLOWS(prov, flags) (prov->url_flags & (flags |
(flags << CAMEL_URL_PART_NEED) | (flags << CAMEL_URL_PART_HIDDEN)))
#define CAMEL_PROVIDER_NEEDS(prov, flags) (prov->url_flags & (flags <<
CAMEL_URL_PART_NEED))
#define CAMEL_PROVIDER_HIDDEN(prov, flags) (prov->url_flags & (flags <<
CAMEL_URL_PART_HIDDEN))

It doesn't imply needs as such, they're mutually exclusive more or less.

They both imply 'allows'.  Hidden means it will be used in the url and
maintained by the account editor, but not shown anywhere.

You almost certainly don't need it - another hack for connector.

(you may need to dabble with it if a hostname:port+username doesn't
identify your resource, but to be honest i dont know how that works
either).
