I see many articles warning not to deeply nest selectors in sass. Doesn't gzipping your resources mitigate that problem?

File size is a moot point with regards to long selectors - they are just a bad idea. [1][2] I am a fan of BEM to keep things sane. [3]

Nesting selectors ties the css to your markup. These styles are not reusable components, but one-offs for that particular snippet of html. Look how bad it can get: https://github.com/edx/edx-platform/blob/master/lms/static/s...

It's basically replicating the html nesting.
