We are here to inform you that we released Doorkeeper 5.3.0 with a bunch of fixes and a long-awaited feature: customizable models. Since now everybody can extend Doorkeeper models (AccessGrant, AccessToken and Application) without hacks or monkey-patches (no more prependm yeah!). By default it still uses it's owned classes, but you could change any of them by setting corresponding configuration options. More info you could find here: https://github.com/doorkeeper-gem/doorkeeper/pull/1345.

So far it's implemented to be backward compatible with older versions of the gem we still afraid of some specific issues, so your reports and PRs are welcome. Stay tuned!
