I would go even further, and explain why tracking what files each
package installs is by far not sufficient to support binary packages.
Several people have showed up throughout the project history, willing
to add support binary packages by assuming that simply tracking which
files "make install" installs will be sufficient. But that's forgetting
all the optional dependencies problems, and various other things.

We had a write-up about this in some report of a past Buildroot
Developers Meeting, with some good arguments. Would be nice to dig that
up and summarize these arguments in the doc.

Best regards,

Thomas
