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.
