It is EXACTLY as backwards compatible as it needs to be, both for now as well as back in 1995 and probably earlier. Unless you can point to a currently running system, or even one back in 1968, that required a two digit year to function in order to achieve proper FTN based digital communications, then I will still maintain that the current proposal stands and is indeed TRULY backwards compatible. By you limited definition nothing is backwards compatible including 8-bit systems that require a 2 digit year for their punch card IO database.
Please feel free to fold, spindle and mutilate THAT.

Living and learning.
Life is good, Maurice
