In line with the recent "Rescuing Customs" chat, I propose the following: Whenever someone uploads a custom, have them check a box that specifies whether they are willing to have others modify and re-upload their CDLC with either a link to the original post, or a blurb thanking the original author(s). You could set this to default on in an Account Setting, if people wish to do so for all of their custom work. I see this as an important piece to allow the distinction between people who are happy to open-source their work, and those that want their upload to be the final, definitive point. This way, we can have multiple people working on the same custom without worrying if the author would become upset. For example, it could encourage people who are working on something like a discography to separate tasks, and have one person transcribe the notes then pass on tones to a tone expert, and then on to a bass slapper, etc.
