It does annoy me that these were not made immutable. The safest way to create
an object is still either with an object literal or new SomeFunction;
I'm not convinced that Object.create added anything of value to the language,

its use for general object creation.

I disagree. Object.create is the foundation of a system of delegation.
This was the brilliant idea that JavaScript borrows from Self.
The best technique available now for general object creation is
Object.create(null), which allows for making objects which do not
inherit from Object.prototype. This is a better defense against
unintended inheritance than use of Object.prototype.hasOwnProperty,
which has multiple hazards.
I agree that the primordials should have been frozen, but as Brendan
says, that ship has sunk. But a smart library can now do that job, so a
page can elect to have the benefit of frozen primordials if it wishes.
