Vendoring is nice, and I usually prefer it, but you don't always have the time or people for it.
Vendoring + custom build system (Bazel?) for everything is basically googles approach, if what I have read is correct. Definitely better than everything we have, but the resources for it are not something most can afford.
P.S also what mrcus said, if we trust the upstream build process, we may as well trust their binaries.
Kinda relevant, as I saw few comments about how safer languages are the solution.
Here[0] is a very simple example, that shows how easy such supply chain attacks are in Rust; and lets not forget that there was a very large python attack just a few days ago[1].
