This has come up tangentially in a couple of threads now, and there seems to be at least tacit agreement that the plural doesn't make sense anymore now that we've seen how integrations/extensions will work.
I'll be posting an alpha later today, but before that I'd like to do the reactors->reactor rename of the python package to keep everything consistent. This stuff hasn't been in a release yet, so I don't think there are any backwards compatibility issues, but if this will cause problems, please follow up and I will create an alias. --Rafael
