To be fair to the soothsayers, you could find out you're wrong about reentrancy after the code is in production for two years and some records in the database start having garbage sporadically.

There are some categories of problems where results are king, and some where humility is wiser.

Completely agree. I read your comment as: "There exist OPs so far into the stupid space and senior colleagues far enough into the competent space that good advice may not be immediately apparent to OP, even through the lens of a first implementation." That's spot on and the example you cite is a good one.

It's just so hard to advise here without knowing more about OP and the senior colleague. (That should be the title of the novel "OP and the Senior Colleague.")
