Your assertion that dependencies are the cause of the bloat is only trivially acceptable if, at least, every dependency actually contributed into the binary size, nevertheless in a significant manner. Thus it is a counterpoint.

That makes zero sense. That's like saying your luggage can't be too heavy because it contains a feather. Think about this super hard.

So I'm asking for actual proof, like a disassembly, or analysis through other tooling.

You think you need disassembly to see file sizes?
