Not really. I think stylesheets are usually cached by the browser, and
they're not reloaded unless you click on 'reload page'

I really prefer working with the actual file that is being used. If we
want to compress something, better strip out all that php comments that
are parsed for every page :-)

About css's, as they can be always overridden by the theme, you can try
to merge all of them together in an optimized one for your production
sites -all that css element's overriding is what actually takes time
when rendering the pages...
