I still believe that true innovation succeeds in the Linux world. It
is only that there is no true innovation in that particular patch.
As for Solaris copying the idea: They actually do the mistake which we
could avoid so far. They have dozens of s-bit programs that are known
to support stack-exec exploits. Are they fixing those? No. Instead,
they offer a supposed catch-all solution, and now wait for somebody to
find the remaining back door. I'm pretty sure there still is one.
