In my mind anyway, the idea is something like https://railslts.com/ but for potentially every other gem in your gemfile. We would provide security patches, bugfixes, features, documentation, training, version upgrade scripts/documentation and so on to subscribers.
I really like the accumulated credit for features, maybe a system of like: request feature, we put a "credit" value on the complexity of the feature, then companies/people can pledge credits/money for it would work?
