Please add some sort of private Github/Gitlab for each asset with sources on the store :
- Assets will not get deprecated, customers can do their own maintenance and share with others.
- Boost the community efforts (plugins, tricks, documentation)
- The asset home page / documentation can be the source control wiki
- Accessible only to asset owners, integrated with unity login systems. - Assets with source should be non refundable.
- Optional opt in by the asset publisher, integrated in the publisher forms
- with integrated public wiki / static web site
- Hosting : Gitlabs has free basic private repositories so maybe something could be done with them without incurring hosting costs for you guys. Gitlabs has some login integration points, to be investigated. There is your own collab too that could be interesting.
