File or directory names starting with "." are not special and don't have
a higher security risk (I'd like an example of this if I'm wrong). They
reduce screen clutter. To me disallowing them is a broken implementation
arbitrarily restricting my naming conventions that have existed for
decades.

That is very wise. Is it difficult to distinguish "^\.\." from "^\.[^.]"
(using REs) or two dots from (one dot followed by a non-dot)?
