@agbeltran this looks good but @louise-davies raised a concern in today's sprint review about whether or not this needed to go in the 1.0.0 release (which could cause difficulties since it's already been released). Apologies if I misremembered that, Louise, please feel free to jump in and clarify if so.

[agbeltran]

@sam-glendenning @louise-davies let's merge this in at the first opportunity

[sam-glendenning]

I'm happy with it, I believe Louise is too so will merge now
