For a module that is implemented as an extension, I get only the
module's definitions/exports:

 localhost.localdomain% mzscheme -L mzssl.ss openssl
 Welcome to MzScheme version 299.14, Copyright (c) 2004 PLT Scheme, Inc.

 (ssl-close ssl-listen ssl-make-context ssl-connect ssl-accept/enable-break
  ssl-make-client-context ssl-load-certificate-chain! ssl-client-context? 
  ssl-available? ssl-connect/enable-break ssl-load-private-key! 
  ssl-load-suggested-certificate-authorities! ssl-addresses ssl-accept 
  ssl-load-verify-root-certificates! ssl-set-verify! ssl-listener?)

I thought that would be the case for SWIG-built modules, too.

For a Scheme-implemented module, it's true that all of the module's
imports are listed (as well as the identifiers that are defined in the
module). In that case, other functions --- such as `identifier-binding'
combined with `namespace-syntax-introduce' --- could be used to
distinguish definitions from imports.
