But the same argument can be made about all of the PCMCIA drivers. It's been a long time since any new mass-market hardware with PCMCIA slots has been produced. Even if you count in the (non-express) cardbus, the same argument holds true. I personally haven't used any of those cm4000/cm4040 in ages. But what particularly the last decade of my professional career has taught me: There are typically always more users of legacy tech out there than you would imagine. The question is whether those users are relevant enough for today's kernel maintainers to care. This isn't meant to sound bitter - I'm just stating facts. It can be a valid "developer resource economic" decision to not care.
