Either is certainly possible, but if there are established warning levels, it is reasonable to expect that level or stricter. A reviewer should be able to examine the library as any Boost user would. Why would following a warnings policy be different unless a specific exception were incorporated into the policy?

A reasonable conclusion is that the submitter chose to ignore established Boost norms and doesn't care about the effect on reviewers, your assertion to the contrary notwithstanding.

If trying to test against the library produces myriad warnings at established Boost warning levels, as a Boost user should expect, the reviewer shouldn't judge the usability of the library highly.
