It should be noted that the salt in v6 signatures also helps to protect against fault-based attacks. See https://eprint.iacr.org/2017/1014
I'm not entirely sure that the v6 salt helps in this case - it influences the final digest but the fault attack then operates on that new digest. I've read section 9. Countermeasures and couldn't find any mention of salt being effective.
Of course, the obligatory disclaimer: I'm not a cryptographer and it'd be nice to hear one voice their opinion and arguments.
