How many of these criteria were applied to export? :o) And to illustrate
bias again, why weren't:

8. can it be implemented efficiently?
9. could users pay for features they're not using?

there? That's where policy_ptr might be in better shape than shared_ptr.
If I were around, I would have made sure those criteria are included as

Hey, nobody disparaged anyone; I took time to explain how I myself am
biased, and how others might be biased, and I also gave an example of a
potential bias. From there to "evil spirits" it's a long way. Maybe
"conflict of interest" ain't the proper syntagm, and "unintentional
bias" would be.

Library design and appreciation is subjective; that makes it hard to
stay unbiased towards a particular design. I know I am biased myself,
albeit not to the point of being unreasonable. Naturally I'd believe
others might be as well, and I don't think I dispense offense in saying

At the end of the day, it's very true: one has to sell one's design, and
that happens exactly because appreciating ("buying" :o)) a design is an
experience that has a strong subjective aspect to it.
