Earlier quoted context omitted.
You could call it a side-grade. We're also allowing users to add a worker dyno and use up to 18hrs/day of `heroku run` and scheduler one-off dynos as well. All told you can get quite a few more compute-hours for free applications now than before.
You can call it what you want, but for what I (and others presumably) use it for, the 24/7 uptime is essential. Sure an argument can be made for needing to pay for 24/7 uptime, but it is very clearly a downgrade in such a case where such an argument even needs to be made!
And all that for only $7/month. Seems reasonable, for an essential service.
