It's already fully modularised ;)

JASPIC is not an overal comprehensive single framework. It already has the
concept of a "profile" in the spec. Each profile is completely independent
of other profiles.

A profile basically says how a certain other spec should behave with
respect to authentication. I.e. the Servlet Container Profile says this
about Servlet. The SOAP profile says this about EJB, etc.

In the case of the web profile, as Ondrej mentions correctly, only the
"Servlet Container Profile" would have to be made available in the Web
Profile.

Kind regards,
Arjan Tijms
