OK most of these questions are going to be answered by the fact that
CentOS is a rebuild of Red Hat Enterprise Linux. If Red Hat Enterprise
Linux does not have something in it's base packages, it isn't going to
be in the CentOS package set.

Because Red Hat put them in a package set which is not shipped as
source to CentOS to rebuild.

Because Red Hat only did a build of GNOME for RHEL-8.

The way modules and other layout changes come with RHEL-8, the old
tools which are used for announcing updates do not work. Please see
other threads on this for the request for help on this.

EPEL is a volunteer project and there is no ETA because it is up to
the volunteers time and effort to build things.

You are probably looking for packages in PowerTools. Please enable
this as this will also fix your audacious problem.

Because RHEL shipped with it that way.

PowerTools is a set of packages which Red Hat ships as
CodeReadyBuilder channel fo RHEL-8. It contains packages which are not
part of the main distribution and would not have 'technical support'.
[AKA if lynx were shipped in RHEL appstream it would have certain
support levels for security and application fixes... it has few of
those in Code Ready Builder.] For CentOS it is meant to communicate
that CentOS is a rebuild of RHEL and certain problems may not get
upstream fixes.

Because RHEL shipped that way.
