Not if there are strict(er) rules to what is "a valid result". Is a
valid result just those that are not returned immediately with an
error, or is it all work after validation? Is it strictly about the
work being done, or is it to safe-guard against "wrong-doings with
credit"?

At this moment a valid result is work returned before the deadline and
without errors, but prior to validation.

E.g. at this moment - taking Seti again as an example - there are
Linux computers out there that return valid results that show zero CPU
time, thus claim zero credit. If paired against another box claiming
zero credits...

There are also all_platform computers out there that still run BOINC
4.xx, which categorically claim zero credit. And usually everyone in
that group gets those zero credits, as the work is validated as being
correct.

If it's strictly about work being returned immediately with an error,
then the present restrictions may be adequate.
If it's to safe-guard against zero CPU time claimers who apparently
(after validation) return good work, does there need to be something
else done? What?
If it's to safe-guard against zero credit claimers/zero credit
granters? The best solution is to get them to update to a newer
version, but how?
