IS there any reason not to include javascript in my own post's embeds?

That class is used for styling purposes so that you could apply styles specific to when JavaScript is not available (either not supported or is disabled), and when it's available (supported and enabled). And in most cases/implementations, when JS is enabled, the no-js class will be replaced with js .
