With the larger droplet it looks like we should be able to add these backends again, along with the entire PS package set.

[hdgarrood]

Oh, just to clarify, I don't want to restore the backends, I just want to include the relevant libraries in the package set and include the relevant JS libraries as shims so that we can have all of the above work without having to reintroduce backends.

[thomashoneyman]

Sorry, I misspoke. I also meant reintroducing these libraries, not as “backends”, but just being available in general.

Is this something we're still interested in doing?

[hdgarrood]

Provided that the relevant libraries still work in 0.15, I think it'd be nice - especially given that people had to put work in to get these into Try PS in the first place.
