At a level it does, but it can also get out of control.

I'm objecting to:

If specific problems are present in 6.1 and are going to _really_ hurt
the user then they should be mentioned (if they happened to be in 6.0 as
well, oops).

However, we should not allow PROBLEMS to accumulate just because they
are still present -- heavy editing is required to ensure that the
PROBLEMS file is both relevant and focused (Several releases back I
deleted chunks of README as, although technically correct, they were
simply not relevant).

Actually, somewhat perversely, that is a good thing.

It leads to a cluster of bug reports that provide a strong pointer to a
specific problem that is hurting many of our users. If we introduce
mechanisms that artificially filter out this information we end up with
a skewed view of our user base.

Definitly no.
