What services require transport of packets with RFC1918 source addresses across the public network? I can think of esoteric examples of things it would be possible to do, but nothing that a real-world user might need (or have occasion to complain about). Do you have experience of such breakage from your own customers? It would be interesting to hear details.
Check the archives, its been covered every time this issue has come up... a. Intra-provider links using RFC1918 addresses and MTU changes/PMTU discovery b. Traceroutes TTL exceeded packets across RFC1918 intra-provider links People used to have lots of problems with @Home customers trying to access their websites if their filtered RFC1918 addresses using large MTU connected servers (i.e. non-ethernet). Ok, so @Home is out of business, but I'm sure there are other similar cases which would break.
