I suppose that the utility of keeping the period with the extension is
to allow it to be appended to some other extension-less file name.  And
likewise the utility of keeping the period with the file name would be
to allow some extension to be appended to it.

I guess it depends on your perspective.  I see the file name base and
extension as symmetric components on either side of the period.
