The relevent point IMO is the part about "10% perf improvement is a nice feature, a 10x one is invaluable".
Essentially you have the svn branches vs git branch scenario here: svn branches were fast enough and people worked around the perf issues just fine with various strategies, bit git branches come in and change how branches are used altogether.
So sure, you can just break down the project in a lot of libs or sub projects (that's what we do here: our app is broken down in hundreds of smaller ones so we never build the whole thing), but what if you didn't have to?
Extreme case, in a magical land of fairies and unicorns: what if it was possible to git clone 100 million lines of code instantly, load them up in your editor (all of it) instantly, do all refactors/searches on the entire code instantly, live (without caches), and at every single keystroke rebuild everything, every time, with zero latency. How would that change your workflow and some architectural decisions?
This is not a real question, but just something to think about, when we're talking about a compiler that could be 10x (or more) faster.
