I'm definitely in favor of not pessimizing code and assuming you can just hotspot optimize later, but I would say to avoid reusing objects and using sync.pool if it's really not necessary. Go doesn't provide any protections around this, so it does increase the chance of bugs, even if it's not too difficult to do right.

I mean, do it if it's worth it. But the parent seemed to imply everyone should be doing this kind of thing. Engineering is about tradeoffs, and sometimes the best tradeoff is to keep it simple.
