Ah, we're talking about different things then. You're talking about building
and shipping 10,000 libraries. I thought we're talking about building a
project with 10,000 dependencies.

That's just nonsense. The OS doesn't matter.

Reproducible here refers to you get a bug report about build number 49121,
but you're already on 56192 internally. You need to be able to rewind back
to 49121. The entire state of the project is a unit, you can't treat
dependencies as their own separate kingdoms which you build, "install", and
forget about.
