As anyone who has ever run Kconfig knows, linux is already very well modularized, and disabling unneeded logic at compile time is already easy Yet in the interview, Linus says the kernel is getting bigger and slower because of new features, which presumably not everybody needs. "[W]e are definitely not the streamlined, small, hyper-efficient kernel that I envisioned 15 years ago...The kernel is huge and bloated, and our icache footprint is scary. I mean, there is no question about that. And whenever we add a new feature, it only gets worse." He isn't talking about code that can be compiled out or left unloaded if you don't need it. He's talking about code that ends up in your instruction cache whether you need the features or not.
