FWIW, I use it in a handful of places in my user-init-file to avoid
copying the interactive spec of some command I'm mimicking.  As a poor
example, I've written a couple of commands akin to browse-url, whose
interactive-form I set to the value of (interactive-form 'browse-url).

This is obviously no reason to hold back on obsoleting the property, but
I'm still curious whether there's another way to be as lazy as I
currently am about copying interactive specs in this way.
