If you only deal with structs and want equality-by-address
semantics, then yes, this is safe. The addresses of cdata objects
don't change.
[The paragraph in the docs mainly deals with cdata objects that
generally provide equality-by-value semantics, except when used as
hash table keys. I.e. cdata numbers and pointers.]
