Indeed, the spe_program_handle pointer is unique, too. However:

1) if we don't use embedded images, a call to get_image() will actually
load the kernel first, so we'd need to add some more cachine logic.

2) With SDK 3.0 (which we are going to adapt sooner or later anyhow), we
don't have access to that any more, or at least not in that raw form.
