You really confused me.  If you don't want it, why mentioned it twice?

You proposed this idea:

> on `.' and `..'.  And so based on that, you or someone else (NOT I),

and then rejected it:

Inconsistent.

If you don't want it and you don't want anyone else to use it, then
do not mention it in the first place.
