I'm aware of this, and I agree.

Yes exactly.

Another path we could go is add a wildcard string instead, for example:
MODULE_FIRMWARE("brcm/brcmfmac43455-sdio.*.txt");
AFAIK there is no driver in the kernel that does this. I checked with our dracut
developer and right now dracut can't cope with that. But he will try to
implement that in the future.
So my idea was to maintain that list for now and switch to the wildcard approach
once we have dracut support that.
