I understand your logic. But I think it's not that simple: Part of being a senior engineer (at least for me) is to educate my less senior peers. And in a sneaky, non-condescending way, that is.

It's usually thursday or friday evening that my team will pop some beers and talk conceptuals. In those informal discussions information just flows, sentiments are shared and fruitful decisions are reached.

Winning and losing battles implies that battles exist. That's bad enough for me.
