Why should it create functions at all? I mean, according to the
following, ECL is free to implement SETF access to slots using macros
or SETF expanders

":read-only x
When x is true, this specifies that this slot cannot be altered; it
will always contain the value supplied at construction time. setf will
not accept the reader function for this slot. If x is false, this
slot-option has no effect. X is not evaluated.
When this option is false or unsupplied, it is
implementation-dependent whether the ability to write the slot is
implemented by a setf function or a setf expander."
