I was simply stating my discomfort with hard-coding a particular value for the current architecture into R6RS, as opposed to, e.g., providing procedures for querying the architecture, as you yourself suggested in your prior message. There are usability reasons (flexibility, the possibility that any particular value might seem quaintly dated in 5 or 10 years) and philosophical ones ("there are only three numbers: 0, 1 and infinity" that should be hard-coded in a design/specification).
