ISTM that you are missing the "why" part of this change in the commit

"make tinyconfig" is the real target here.  The other (tiny.) files are just
implementation details.
We can't put all implementation details into help messages and it's not
difficult to find that the (tiny.) config files are merged to make the
final .config file.

So what is it that you are trying to solve?
