It was R6's goal also. But it didnt accomplish the stated goal but just introduced more incompatibility into the overall Scheme ecosystem. But instead letting all implementations at least get up to R6, they now have R7 on the horizon. They afre churning standards out more quickly as implementors can implement them.

And frankly, I dont see what the point will be: R7 small is not much differrent than R5, so it is kind of pointless. R7 big is as big as common lisp, and very few implementations will have the resources and the willingness to implement it and discard their current non-standard APIs they had for years. And even if the majority of them manages to implement R7, they will finally reach the point where Common LIsp was 1994, with no added value over Common Lisp, provided of course they dont decide to obsolete R7 also and get to R8 before that.
