But isn't there still the kernel of an idea here for a package management system that intelligently decides to build based on platform? Seems like a lot of performance to leave on the table.

Rebuilding from scratch also takes longer than installing a prebuilt package. So while it might be worth it for a heavily used application, in general I doubt it.

Also I think in earlier days the argument to build was so you can optimize the application for the specific capabilities of your system like the supported SIMD instruction set or similar. I think nowadays that is much less of a factor. Instead it would probably be better to do things like that on a package or distribution level (i.e. have one binary distribution package prebuilt by the distribution for different CPU capabilities).
