agreed.

However:
 - who is creating this tarball?
 - who is maintaining it?

But you propose that an additional tarball is needed. Or not?

not really, because you just change the work to maintaining the headers
tarball. Instead we can also include it (same amount of work for us (me))
and the users do not have to download this extra tarball.
If the Tcl/Tk people fix their problem, we stop to fill in new headers.

But generating a new tarball is the same work, or not?
I don't see the difference... (please speak slowly to me... :-)
