Recently, when trying out the X-Payments module, I was delighted to have everything work correctly.... this from someone that stopped trusting any module prefaced by the letter X.
On closer look, it was noticed that this module version (originated by Wishcraft) was associated with several names supporting the module , including Wishcraft, Mariann (themer) if I remember, Mamba, and someone else.
This was a good example of successful cross disciplinary module development (teamwork) as you mentioned, that while worked for Wishcrafts situation, would make perfect sense for just about any other module.
Prioritizing resources by module value would make it manageable.
