Well propagated-inputs won't increase size of a package, they bring some
of its inputs when build other one to remove the need to list those some
inputs as inputs of the other one.
Consider gtk+ and mousepad:
gtk+ propagated cairo, freetype, pango, etc.
so I don't need add those inputs to mousepad, and if gtk+ doesn't
propagated them then I must add them to mousepad because those are
actually needed (because pkg-config check them and need link flags
from those dependencies of gtk+).
But for runtime, when substitute of mousepad is available, if we split
thoes packages with "dev" outputs, guix size mousepad would still be
something like:
...
/gnu/store/xxxx-mesa-23.1.4
/gnu/store/xxxx-freetype-2.13.0
/gnu/store/xxxx-gtk+-3.24.37
...
It won't include any "dev" output of its dependencies packages, since
development files are not referenced by mousepad's binary, so the size
of headers and development files is saved (won't be substituted).
Only when substitute of mousepad is not available, you'll start by download
mesa-23.1.4-dev, gtk+3.24.37-dev, etc. And after build, those "dev"
outputs can be GCed immediately.
Hope it's clear now!
