Given that 64c/128t CPUs are currently available, and that many devices (nvme, many NICs) desire to map 1 MSI-X vector per core, or even 1 per-thread, it is becoming far easier to see MSI-X interrupt setup fail due to msi vector exhaustion, and devices fail to attach at boot on large system. This bump costs 12KB on amd64 (and 6KB on i386), which seems worth the trade off for a better out of the box experience on high end hardware.
