> bundle all of their dependency libs

Mother of God! Very popular argument. No one cares (in terms of architecture).

> vulnerabilities are found in their bundled libs!

Yes, god only knows how entire install base of mac and windows machines works today (this problem is not as big as you try to present here).

Your arguments like debate about linux monolithic and minix micro kernel architecture. Minix is more advanced in theory, linux (not linux desktop) working in reality.
