First of all, Pawnman was just simply answering someone else's question about his record, and he got unfairly lumped in with the other poster, who always sounds like he is trolling or humble bragging. Pawnman has been around for a while and has contributed greatly here.
I tend to concur with you; however, in other career fields, you can be seen as a scumbag for repeatedly not submitting your own package when there are calls for nominations. Your boss is typically too busy with his own job to actually know what everyone does or submit his folks. I haven't met an O6 that will actively mentor his people or submit them for anything. It's not right, but it is what it is. So by not submitting yourself, you are killing your own chance to be competitive. In the past, I've been at units, where leadership decides who to submit depending based on popularity contest or if they had a shot at the HPO on-ramp, regardless of job performance.
And just to be clear, when we say FGO OTQ/OTY, we are talking about at the O4 level.
