We have created a branch off of Boost Campus in our git. However, it would be great if we could subtheme Boost Campus instead of Boost, so we could get updates for both.
Just checking to see if this is so-called supported behaviour - subtheming a theme that is itself a subtheme already - and what kind of issues are foreseeable?
Or is it easier to just have a separate Boost subtheme that is initially a copy of Boost Campus. (Which would mean losing future updates to Boost Campus unless we do manual merges).
