I actually considered that, just didn't call its name explicitly.

I'm also not sure how I feel about it. Having people using multiple versions of the app in the wild seems wrong. Also, many apps have a server component which has ongoing costs and as a result user who choose not to pay for an upgrade will still cost you money and maintenance of the server for old versions OR they will lose functionality. I guess it can work for offline apps.

Many apps have a server component to justify charging for a subscription. Sure you might need a server if you're doing something novel, but apps that operate on documents should just use iCloud, Google Drive, Dropbox, etc.
