Is there any possibility recursively by dir propagate Emacs settings like .dir-locals.el per dir?

Is there any possibility recursively by dir propagate Emacs settings 
like .dir-locals.el per dir?

For example it is useful set file encoding in root of software project
instead per file (-*-...-*-)/dir (.dir-locals.el) settings.

Some answer I found in manual:

    If you put a file with a special name `.dir-locals.el'(1) in a
directory, Emacs will read it when it visits any file in that directory
or any of its subdirectories, and apply the settings it specifies to
the file's buffer.  Emacs searches for `.dir-locals.el' starting in the
directory of the visited file, and moving up the directory tree.

I have question how this work:

I) 1. visit to file
   2. check for ./.dir-locals.el
   3. if ./.dir-locals.el not found, check for ../.dir-locals.el
   4. if ../.dir-locals.el not found, check for ../../.dir-locals.el
...

or

II) 1. visit to file
   2. check for ./.dir-locals.el
   3. check for ../.dir-locals.el
   4. check for ../../.dir-locals.el
...

I like II) variant.

If I) right how deep .dir-locals.el can include upper .dir-locals.el?

I check this myself in morning, but now time to sleep...

Emacs uses I).  See locate-dominating-file.

I don't think you can.
