But sometimes, we do look at them. Especially in an embedded context.
One example could be things like stack consumption analysis. Or to
answer the question "how much code size do I pay for using this C++
feature?". "Did the compiler correctly inline this function I expected
it to inline?".

And if the linker gives me a "duplicate definition" error, I prefer that
it is located in 'editor.o', not '3d3901cdeade62df1565f9616e607f89.o'.

The main reason I'd never write Makefiles the way CMake does it is that
CMake's makefiles are horribly inefficient...

But otherwise, once you got infrastructure to place object files in SOME
subdirectory in your build system, mirroring the source structure is
easy and gives a usability win.
