My main issue is simply protecting DMD from someone, years later, asserting some 
sort of claim over it. Also, I need to be able to deal with issues as they come 
up, and some contributors may be unreachable (and this has happened multiple times).

With copyright assignment, these issues go away.

I don't know why any contributors need to be concerned about the Boost license, 
or the copyright assignment, affecting them. As far as credit goes, the github 
repository provides ample credit to who did what, and in fact I encourage people 
to use their real names on it so that they get the credit they're due.
