That's the official marketing line. RH now ships their supported tomcat server as an SCL, even on RHEL 8, calling it "jws5." This may be because they still ship tomcat natively in the no-default-stream of the pki-deps module. (They don't want you to know that the easiest way to get it is `yum install 'bundled(tomcat)'`, nor can you repoquery disabled modules.)

Agreed. I thought the `-syspaths` sub packages fixed the usability if SCLs pretty well, though.
