Addon Libraries Question

[NeuroticPixels]

Hey, I hope you're all doing great today!!!!
I have a question about libraries.

Some addons, especially ones that haven't been updated recently, still contain libraries like "LibAddonMenu-2.0" and "LibStub", etc.

Is it okay to manually delete these bundled libraries if I've installed them separately already?

Or could deleting the bundled libraries cause an addon not to work correctly or at all?
