He said "Said developer got called out in a meeting with many others present and didn't even appear to feel embarrassment or apologise."

In the noted case there was no overt penalizing (at least that we heard about) nor was there shaming (the person was apparently "unshameable"). Therefore your post falls short of it's target.

That said, in general, I agree with every word you said. I especially like the "frankly [it] is just plain rude." - good manners (etiquette) can make a world of difference in a workplace but have largely fallen by the wayside in our culture.

The "got called out in a meeting with many others present" part is something which I don't think should have happened at all—regardless of whether or not the developer in question felt shame. No good can come from publicly calling someone out in a meeting like that. It's childish and unprofessional.

I feel the best courses of action are to remind the developer privately and/or to make a general "remember to read the docs" statement to the whole team in the meeting.

Yes, but we don't know what the OP meant by "called out": it could have been as simple as one person asking "Did you read the documentation?" and a long following uneasy silence, or it could have been quite vicious, e.g., the documentation's author ranting at the developer for not reading the docs, a manager dressing him down for his failure to do so, or even worse.

But we don't know, so while your point is well-made it is tangential to the discussion. Nonetheless you reveal a well-developed attitude about people and groups that would be very useful in management.

As an aside, the OP's description of the developer in question paints an individual who is most likely not as self-aware as you are: indeed he/she sounds like someone who is quite hardened and aggressive in his ways. Sometimes you must unfortunately pop such people on the nose to get their attention.

Compare yourself with the aforementioned developer - which of the two is more likely to be/become a manager? Such an opportunity is not likely for him but is something that probably lies in your future, waiting, if you haven't already gone there.
