I was under impression that I have fully modular USB. Still:

It's just a quirk of the build machinery.
The built-in.o file should be 8 bytes or so, with nothing
really in it.

Not so. Randy, you missed the line for pci-quirks.o. It really is a
non-trivial object file and it really goes into the main kernel.
That's because it actually is a PCI driver, living in a USB source
directory. It handles the quirks needed by various PCI-based USB host
controllers.

yes, but it still costs extra vmlinuz build when just to rebuild of a single
module (or subsystem as was in this case) is needed. And this implies also
reboot - how should one know if this is safe to leave current kernel with new
modules?

No, it's something different:
Note that drivers/usb/host/pci-quirks.o is built non-modular since it
won't work modular.
