I wonder if it is possible for the text property keymap
to remap yank to my-yank, and have this affect bindings
of yank that come from the global map or buffer local map.
Does this work?

    Much better is some system like fill-paragraph uses where the generic binding
    looks for `fill-parapgraph-function' to do the work, which modes can
    override.

It is very useful to set up these hooks in specific places
where we see we need them.  However, we can't expect to provide
these hooks for all the situations where someone wants to override
a certain command for certain text.
