Question

This issue is important especially for embedded development. Exception handling adds some footprint to generated binary output. On the other hand, without exceptions the err

We don't generally care about binary bloat, but if you get too much bloat then you thrash like crazy, so you need to be careful.

Just keep the binary reasonable (depends on your setup).

I do pretty extensive profiling of my systems.
Other nasty areas:

Logging

Persisting (we just don't do this one, or if we do it's in parallel)
