In light of Heroku's free-tier sunsetting, is Heroku planning on providing a way to redirect apps to another domain other than through code? Currently the docs indicate that the only way is for a server application to return a 301.
Background: I originally relied on the automatic DNS name [appname].herokuapp.com for a small project (a terrible idea in retrospect). Now the plans to get this off Heroku just got a bit of urgency after the announcement about removing the free tier.
But most of my users (many of whom are less technical) still use the [appname].herokuapp.com because of bookmarks, habit, etc. It's a bit silly to pay $7/month for a redirect, but if it goes away the trouble it will cause some users is tangible. My original thought was "just train the users"; but given that this is a progressive web app (which can cache data and sort-of work without the server) makes everything even more problematic.
