Fully agreed. Probably a lot of these CONFIG options should be just dropped.
They are quite user unfriendly with very little gain.

It seems like there is unbounded growth in different name space options
which also implies unbounded CONFIG growth. At least they should be all
consolidated into a single CONFIG.
