weblogic 12.2.1-0-0 wlclient.jar file question - why are internal pom files included in this jar?

I have a question regarding the differences between the weblogic wlclient.jar file contents version 12.1.3-0-0 and 12.2.1-0-0....It appears the 12.2.1-0-0 jar file now includes internal pom files whereas prior versions, did not. . .

Some Background

We are using Artifactory as our component repository and when we try importing the 12.2.1-0-0 wlclient.jar file, the 'default pom' file selected by Artifactory is one of the internal pom files that specify a parent <- child component relationship….. where before (for prior versions of weblogic), we were able to specify our own default pom file based on our requirements for internal Artifactory component deployments since prior versions of wlclient.jar did not include internal pom files...
