R7RS-small is, in almost every way that matters, a step backwards from R6RS.

The proposed standard fails [...] to make substantive improvements in Scheme as a language. In essence, the standard fails to justify its own existence.
As a language, the proposed standard is a substantial step backward from R6RS in usability and fitness for purpose. In the precision of its definition, and in the completeness of the features it does provide, it falls short of that standard as well. (I am very aware of the R7RS small language / large language split; I am referring to the internal completeness of the features chosen for the smalllanguage in their own right, and their usefulness as a basis for the large language).

R7RS has made a great step forward from R5RS however it looks a big step backwards from R6RS. The goal seemed gluing the gap between R5RS and future RnRS, and it made a lot of decided stuffs undecided again.
I think language specification should not look back that much even though R6RS seemed too progressive. I hope WG2 will decide dropped off stuff again.
