I think the proposed practice would also apply to toolsets.  In fact
I think its a lot easier than improving a library itself.

Someone decides to add a new toolset.  He has the the current
release (stable) version on his desktop.  He builds the whole
stable version with his new toolset.  Any failures are particular
to the toolset.  So he may fiddle around and minimize them.  At
that point he builds markup for that toolset and merges it (or
requests a merge into the stable branch).   Maybe there is a re-test
with the new toolset. But likely, since its a new toolset, he is the
only one with it so that pretty much has to be the end of it unless
he's willing to test it on request (which he probably be expected to do).

Now that is going to leave a situation which some people aren't going
to like.  The "Next" release is going to have a new toolset with
lots of failures (typicly).  The question isn't whether its perfect, the
question is whether the Next release is better than the current one.
Well, it IS better even though it has more failures.  The total
breadth of applicability is broader than the previous version.

We can't make releases perfect no matter how long we stretch
out the delivery time no matter how much we put current development
on hold no matter how many times we test.  We can guarentee
the each release is better than the current one and we should
do that as frequently as is practical.
