I certainly wouldn't insist that people add it but equally pushing to
remove it too strongly seems like the wrong thing, at least as a general
comment rather than a specific one.

It's not just platforms that use these things though - there's things
like the SolarFlare NICs where the firmware update mechanism essentially
involves exposing a SPI flash as part of a PCI device and we just merged
an ASoC driver for a video card which was reusing some existing IPs and
chips.
