Hmmm... yeah, you can say that, but it still was a failure to
recognize and apply the common pattern and what you're suggesting is
deviating for no good reason.  It demands a lot of cognitive overhead
for something which should be routine and makes the code a lot more
fragile as a result.  Things like this make barrier usages difficult
to understand and verify because it takes away a lot of ready-made
cognitive tools.  So, let's please stick to the known pattern.

Thanks.
