[jbosstools-dev] Facet's not asking runtime/server about libraries - intentional or error ?

Hi, I noticed today that when enabling JSF or JPA on projects neither of them consults the server/runtime about which jars that are relevant for it. dynamic web and the java facet does....why not jpa and jsf ? some runtimes could return an optimized set of jars if this were done instead of just returning *everything* .... I'm i missing something obvious ? what about JPA projects that won't be dynamic web apps ? /max
