[resteasy-dev] Why resteasy.servlet.mapping.prefix

Anyone remember why Resteasy web.xml config setting, resteasy.servlet.mapping.prefix was part of Resteasy arch? It appears in the very 1st 1.0.1 documentation release, so it must have been part of the initial design. Resteasy completely ignores servlet-mapping's, url-pattern, and uses resteasy.servlet.mapping.prefix if declared and @ApplicationPath if it is not declared. Changes may need to be made to this. I would like to understand why this design so as not to implement a change that would break Resteasy in a major way.
