That commentary was apparently written a very long time ago.  The
semantic load feature set has command such as:

(semantic-load-enable-minimum-features)
(semantic-load-enable-code-helpers)
(semantic-load-enable-gaudy-code-helpers)

which are handy, or a user can turn on the misc features one at a time.

The 'minimum features' is actually a list of two minor modes
(semanticdb, and the idle scheduler), plus some code to load in caches
which is only needed when trying to combine with ebrowse.

The idea of a 'cedet' mode is something I'd been contemplating for a
while.  Even though CEDET is "one" collection of tools, each individual
tool (ede, semantic, srecode, etc) is treated independently.
Configuring cross-dependencies between these tools can be confusing, or
so I guess from the questions I see.

Having one master name (cedet) as an interface controlling all the parts
so users don't need to see the individual names might be a boon for
getting configurations working.  The current name set is useful for
development where being specific is needed.

I updated the cedet.el comments to reflect the 'new way' of configuring
things.
