Is your feature request related to a problem or a nice-to-have?? Please describe.
It would be nice to get rid of some NodeJS specific things that makes it better suited for browsers.
one such thing could be the option to remove util.inherits and replacing it with classes that can extends things.
resulting in fewer dependencies and smaller code bundle that won't require the browserified version of util that has an additional of 20 modules and 12 kb

NodeJS docs have marked it as legacy and has this to say about util.inherits

Usage of util.inherits() is discouraged. Please use the ES6 class and extends keywords to get language level inheritance support

Describe the solution you'd like
Change prototype based classes into es-classes
