That's ok.  I don't argue about that.

Yet I still argue "immutable" means "its value never
changes, no matter what", and it will be incorrect to
use that term on something that can change.

How about "read-only", for example?  I think in general
"read-only" means the user can read it but cannot write
to it, though it doesn't exclude the possibility that the
value changes.
