I have no objections to removing the driver, but I think its worth
pointing out the actual year it was written (2010) to put into
perspective how young or old it is. Since this is a USB device,
there are likely still many of these in use on newer machines,
but they are also trivially replaceable.

I checked my series of driver removals to see if there are any
other mmc drivers that I already have patches for, but there are
none right now. There are two drivers that are used on relatively
old PC laptop: wbsd.c relies on ISA/LPC DMA, which become
unavailabl  on PCIe chipsets 20 years ago, while sdricoh_cs.c
relied on a PCMCIA or Cardbus slot that was phased out around
the same time when laptops started using Expresscard instead.
