I think unsolicited ACKs are typically ignored by many protocols. After all, they are notifying us about somethign we are not (or no longer) interested in.  Not sure what the BSSGP spec says about it, but I could imagine that unsoliciated ACKs are to be ignored.

it is indeed a bit inconsistent that an UNBLOCK_ACK or RESET_ACK are now handled significantly different than a BLOCK_ACK...
