There are places in the standard where we have fundamentally introduced gratuitous incompatibility with the R6RS standard “just because it’s R6RS.” An example is the error procedure. Here, there was no reason not to diverge from R6RS’ behavior, especially given that the R6RS behavior is a more expressive, useful form.

R6RS in turn was gratuitously incompatible with SRFI 23, another extremely common SRFI (it is almost always presumed by reference implementations of other SRFIs, even those that predated it). The choice was R6RS, SRFI 23, or both (under different names), and any of these choices would have been justifiable. The WG went with SRFI 23.
