'deleteProperty' was in fact originally called 'delete'. We changed it to
avoid a conflict with the keyword, which occurs when importing the function
(recall that the Reflect.* methods are actually functions exported from a
module). While ES5 made it possible to use keywords as properties, you
obviously still can't use keywords as ordinary function names.

defineProperty is by symmetry with the existing Object.defineProperty
built-in. I believe the symmetry is more important than a shorter name.

Cheers,
