Not having them enabled on all dependencies makes them significantly less useful if your application interacts with the system in a meaningful way. "Just recompile" (glibc + xorg + qt + whatever else you use) is a very hefty thing.

Having them enabled by default also enables devs to ask their users for traces. I can reasonably tell someone to install sysprof or something, click a few buttons and send me a trace. I cannot reasonably tell them to compile the project (+ dependencies). And tbh, even devs cba if they have to jump through too many hoops.

> We talk a lot of energy efficiency these days, to me wasting a 2% only to make the performance analysis of some software easier (that is that you can analyze directly the package shipped by the distro and you don't have to recompile it) it's something stupid.

We're trading all kinds of efficiencies for all kinds of niche benefits all the time. This enables analysis of what is shipped in real use across the whole stack with the alternative being much less useful or a lot more (human) work. To me it's worth 2% and I'm shocked (well... not really) it's not for more people.
