It does not really matter. People ignore the messages unless looking

because the cipher is weaker than expected but not known to

don't care will ignore it even if it's crit.

Is it worth of trouble to do any driver changes then (open question to
everyone)? I'm not sure it is worth of trouble to add cruft to the
driver code for a warning that will likely be ignored anyway.

you can have special commands and talk to the TPM to do the upgrade
even if it is part of the platform and not connected to a standard
bus.

Unless the upgrade command is disabled to not disrupt the platform, of
course.

Sure. This misconception partly came from live discussions at Prague. Of
course it you can have vendor specific commands to achieve this.

Maybe the original statement came from the fact that on most consumer
devices this is disabled?

Thanks
