The stop sign, like "pictures of cows," is another canonical example
presented in the WG2 "Principles and Procedures" document (updated less
than a year ago) of what should *not* be encoded. It's interesting to
see further evidence of how loosely the principles are applied, in spite
of all the protests that UTC is following the same principles in
encoding emoji that it followed two decades ago.

Unless they can be defined as "compatibility characters," in which case
all of them must be encoded without question.

Maybe Google will find it strategic.
