There is at least one proposal for path/trail difficulty in the wiki [1] and at least one that appears accepted and in use [2]. Of course neither of those is an exact match for the Yosemite Decimal System[3] based on a 1930s Sierra Club rating system more familiar, at least to me, in the US. Though the YDS is mentioned under climbing [4] and [5].
