Right, customize-set-value is working but Easy Customizations claims:

(info (emacs) Changing a Variable)

     [State]: SET for current session only.

 You don’t have to worry about specifying a value that is not valid; the
 ‘Set for Current Session’ operation checks for validity and will not
 install an unacceptable value.

Which is clearly not the case in Emacs-26.3

Thanky you
