USB controller discrepancies - questions about correct configuration

In case there is only one USB controller, as dom0 says, does this whole procedure, called “How to enable a USB keyboard on a separate USB controller”, bring any actual security benefit?

No.

Why do I have sys-usb (no-strict-reset=True)? Is that some default for USB, i.e. expected, or have I made a mistake in the past without knowing? What is the right thing to do?

Why enable "no-strict-reset"?

I’ve run qvm-pci to list available PCI devices. Evidentially by default, my USB controller, attached to sys-usb, has the no-strict-reset=TRUE property. Per the documenetation, this “[does] not require PCI device to be reset before attaching it to another VM. This may leak usage data even without malicious intent!” Why would I ever want this enabled (i.e., does this need to be set to true)?
