A support request was recently submitted to MoodleCloud about some of the Boost presets available on https://archive.moodle.net/mod/data/view.php?id=28. It appears quite a few of them aren't working anymore and fail scss compilation. A quick guess tells us they might depend on a variable that's been removed in core, in later versions.

Should they be hidden or removed? The mod/data view used does not show the last updated date, which could give a hint whether they have a chance of working or not.

kellyhowell, please feel free to improve this issue with any extra information you may have received in the request, I've been told marycooch and tsala curate that content.
