What's the current consensus on exempting private network space from source address validation? Is it recommended? Discouraged? (One argument in favor of exceptions is that it makes PMTUD work if transfer networks use private address space.)
IMHO, operators who number infrastructure out of RFC1918 and then permit internet traceroutes over it are misguided and should consider avoiding TTL decrement (i.e using mpls without internet TTL propagation) as a less stressful (for us) alternative to simply filtering.
