I can only speak for myself, but as far as I can see the software is currently at a state where it's difficult to address remaining issues. I haven't analyzed all of them, but the string-based approach, while fast and lightweight, can only stretch so far. If you have control over the source files, things can work pretty smoothly, but if not, you could encounter difficulties, and might be better off using a library that parses the source or analyzes it sequentially. Some options available on Packagist could be sabberworm/php-css-parser and tedivm/jshrink. I don't have experience on either, so I can't say how they compare with this library though.
