That would break a lot of code (much of it not under our control) to
little purpose; it would also foreclose the option to return to using
SPI_ERROR_CONNECT someday.

We go to a lot of effort to keep the SPI API as stable as we can
across major versions, so I don't see why we'd just randomly make
an API-breaking change like this.
