Thank you for the useful explanation!

But if all above only applies to developers (and not to users) I still
believe it is not necessary to add the header, simply because
every developer will manage to download a header from your

I can only state that the more often you repeat it, the stronger I
feel urged to request a code cleanup including documentation
for the header before it gets added.
