Does the 24 copies all get bundled into the final JS file in the case of a browser app?

Of course not.

Also the modules he lists here are mostly for tooling purposes.

Are you sure? I could see multiple downstream versions of utility libraries like lodash and jQuery used in runtime dependencies.

Maybe not as bad as 23, which doesn't seems as likely for non-toolong stuff, but I'd still expect some divergence.
