Agreed as far as the directory semantics staying the same.

However, the question is larger than just directory filtering. What constants gain is lessening the chance that a regular expression gets changed in one location when it needs to be changed in all locations, or it gets changed incorrectly in a code branch which isn't executed often or unfortunately tested. I only used directory filtering as an example.

Thanks for your contribution.
