Re: A new practical problem with invariant sections?
Not any code can reuse any other code, but patch clauses mean code can't
even be reused in code with the *same license*, prohibiting it entirely.
I hope you're wrong and that "code reuse is unimportant and can be
prohibited" wasn't really the rationale.
I think (but I am not sure) that this patch close was to use TeX (the
GNU project use TeX in an essential way although RMS had said he thinked
for long before accepting it; at the beginning Debian had strong
relationship with GNU).
This patch close is almost equivalent to say that code reuse is
prohibited. If this close is explicitely authorized in the DFSG, we
cannot argue that code reuse is an essential DFSG-freedom unless this
clause is changed.
