As a frequent user of the code editor and a builder that surrounds each of the variants I build with their own unique DOM ID so that I can prefix each CSS rule with same ID and eliminate any possibility of style bleed into other areas of the page

I would like to see some of the current CSS validation remarks related to ID use removed. the list includes the following but their may be more:
1. 'don't use ids as selectors' (as it is 100% valid CSS and actually faster in the rendering engine)
2. 'really, 2 ids?' - yes. it is actually common for me. I always surround my variant with its own unique id and there may be downstream ids that I need to modify. pretty common actually.

So that I can have a warning list that is accurate and useful.

The current model results in a warning list that is actually unusable for me because every single line shows up with a warning because I use IDs in every single rule. I understand the models that recommend only classnames to be used, I just don't adhere to them, I write object-oriented CSS for speed and efficiency. IDs in CSS and the DOM are a valid and effective construct if used properly. Given the number of models out there, it is probably best to only warn when rules have actual potential issues.
