> Err, "Google has rewritten the linker twice. Both times with the stated goal to make link times much faster." isn't an appeal to authority.

It is, and a very weak one considering Google has a history of getting people to work on promotion-oriented projects.

It really isn't. You're buying into the fallacy that a FANG can never do wrong and all their developers are infallible and walk on water. All you're able to say is google did this and google did that, and you're telling that to a guy who has first-hand experience on how this and that is actually made. You never mentioned any technical aspect or more importantly performance differences. You only name-dropped Google, and to a guy who already worked at a FANG.

Linking was never an issue.

Want to throw out the technical aspects and performance differences. Judge for yourself:

On initial contribution to the gnu binutils project, the Google developer for Gold claimed a 5x speed improvement: https://sourceware.org/pipermail/binutils/2008-March/055660....

In a public talk on llvm lld, the Google developer for LLD claimed another 5x speed improvement:

There are many FAANG customers who care about link time; some of them are also FAANGs, but certainly not all. You're falling into the libertarian trap of thinking that because it didn't happen in your experience, it could not possibly happen to anyone.
