There was a time where this debate was bigger. It seems the world has shifted towards architectures and tooling that does not allow dynamic linking or makes it harder. This compromise makes it easier for the maintainers of the tools / languages, but does take away choice from the user / developer. But maybe that’s not important? What are your thoughts?
Does this apply if the app is open source?
In practical terms often yes. It can be easier in practical terms to just
LD_PRELOADsomething than to maintain your own patched version of an RPM / APT package for example.
