Been there, done that.  Nothing changes, or is really even properly acknowledged.  For example bug 282071 (https://bugs.gentoo.org/show_bug.cgi?id=282071) was closed as a duplicate, even though it's about ROOT and manager, not about "Examples".  The so-called duplicate 283273 (https://bugs.gentoo.org/show_bug.cgi?id=283273) is nearly 3 years old with no resolution, or even work-around. 

Not even the nearly-as-old bugs submitted to at least document the brokenness are resolved (https://bugs.gentoo.org/show_bug.cgi?id=277688). 

The thing simply has tons of issues that require major pain to work around:

I doubt there are many people that use it, since it's so much easier just to download the package from Apache.org and drop it in /opt, and it just works.

I get that there are issues with the Tomcat up-stream, but it doesn't change the fact that it takes hours to get it working, and updates often break the work done to get things properly in place.
