There no reason to troll at all but they do it...and arguing if he was trolling because I didn't agree with what he wanted or just being rude is just semantics.
Thinking about this a little further; *IF* the devs were only considering the brand new install, with no members or content then it wouldn't matter if they enabled it by default. As the server grows they could disable it, if the load was getting too high. They'd have to have a host that reports CPU usage for that though. Several of my hosts only report traffic and disk usage, not CPU. The dedicated servers and self-hosted servers don't really matter for CPU.
If the server is being upgraded and it already has a lot of users/content/traffic then they've probably already
chosen to enable it (or decided not to) and an upgrade should keep their settings.
The only place that I can think of where it might matter is a forum conversion from something else to phpBB. I might be missing another example where it might matter...
So..maybe it's not *that* big of a deal to enable it as a default...but it'd be easier to notice approaching traffic limits than CPU limits so maybe that's reason enough to leave it as is. On the flip side the pages would load faster but I'm not sure that's enough reason to change for a new install either.

I don't know where that number comes from but a lot of it is network latency (for the redirection) and time spent inserting the edited post in the database (for the edit, and that's mostly because of full text indexing.) Not to mention that the board runs in debug mode so the container is rebuild on every page, which massively impacts the performance.
When we submit the edited topic we go to the intermediate page (I'm not sure what phpBB calls it) where you can choose go to the post or the forum, that page said 1.2s, then back to the topic which was less. Yes, debug matters too and I forgot that it was enabled here. (1.489s for this edit)
