I've worked on many projects, big and small, and the link time of debug builds was never a problem that was worth fixing.

In fact, even today I was discussing with a coworker the inefficiencies of the project's build process, we literally commented that having to only link a huge subproject is a major blessing.

For Google at least, link times are sufficiently important that the company has rewritten the linker from scratch twice--both open source. The Gnu-Gold linker which ships as part of gnu binutils and subsequently the ELF version of llvm's lld.

So although you might not encounter issues with link times (debug or otherwise), it is a multi-million dollar problem for big companies like Google and Apple. Both in resources and engineer time.

I appreciate your appeal to authority, but I worked at a FANG on a project that had over 20 GB worth of static and dynamic/shared libraries.

Linking was never an issue.
