Hi,

no objection in principle. I'm a bit skeptical that it will make a large 
difference (debug symbols probably make up the largest part of the 
space), but I'm open to being proved wrong.

I'd rather not lose the asserts though, and we don't have to. We just 
need to pass -DECM_FORCE_ASSERTS=ON to CMake (see 
https://invent.kde.org/frameworks/extra-cmake-modules/-/merge_requests/574).

Cheers

Nico
