More performance is always a good thing but I don't think targeting CSS selectors is the way to go.

In the case of CSS selectors, performance differences are almost unnoticeable and often come at the expense of code efficiency, maintainability, and understandability.

See this great article on CSS selector performance:

Hey @Devin, I don't pretend to be an expert on this, but things may well have changed since 2009. Also, my testing with gtmetrix also indicates that this is a problem with Drupal:

I do think this should be re-considered as certain Google places increasing importance on performance.
