Right. The plugin will still allow the pdf_output() method to be
exported. This is useful both for folks who want to manually
generate PDFs and for those using older versions of
CGI::Application where the plugin won't be able to register the
postrun callback automatically.
I think these two options (form parameter to request pdf output,
manual pdf generation) can coexist. The postrun callback will be
a wrapper that checks for the existence of the form parameter
before passing control to the pdf_output() method. The user,
however, will invoke pdf_output() directly.

I'm still not sure whether this feature (allow/disallow pdf from
certain runmodes) is all that useful, but if others want it...
I do like the use of attributes rather than having the
user send a table to a config() method or similar.
Thanks for the ideas.
