Follow-up Comment #1, bug #58197 (project findutils):

$find ... -regex ".. | .."
$find ... -path.. -o -path ..
they are not the same in the expression tree.

$find -D tree ...
As we can see from the result of this command, -regex on a leaf alone, two
-path on two leaves. While searching for files, every leaf will be applied, so
I think it is reasonable to spend more time...that's just my opinion
