The truth is somewhere between.  New features tend to be used, and
importantly, they have to be offered.

Anyway, the *per-device* config part will be contiguous.  So we're
talking about pci-specific features.

So far, the only three things make sense to have in a capability list:
MSI-X, the upper 32 feature bits, and the per-device config.

Thanks,
Rusty.
