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.
