Right. I think for most people, if it cannot be remotely exploited, its a non-issue and a deactivated IOMMU is the right choice. Once you really have to worry about an attack vector where your adversary has physical access, its a whole different game anyway and just flipping on the IOMMU won’t safe you.

There is crack the PC open physical access and just connect a device to a readily available connection access. With the later the adversary doesn't even need physical access himself, he just needs an unwary victim.
Smartphones had been plagued by something as simple as a public charging station getting compromised when Android was configured to just grant access to the file system and debug interface without requiring user confirmation. Before that Windows stopped auto playing software because it was used to infect systems from compromised devices.
