@abidh Addressed your comments as best I could, hopefully they're reasonable changes! :-) Unfortunately, I've also done a rebase which breaks the PR as it brings in some incompatible changes that'll need fixed in a seperate PR as it's related to extending the getDataLayout utilities to support the new GPU module that's occasionally in use. But it doesn't make sense to add it in this PR I think, so I'll do so in a seperate one I'll open in the near future (hopefully today) :-)
