Defining rules by a list would be good.  For example:

(defcustom next-error-find-buffer-functions
  '(next-error-visible-buffer         ; predefined function
    next-error-find-buffer-function   ; user-defined
    next-error-last-buffer            ; predefined function
    ...)
  :type '(repeat symbol))

But isn't this unnecessarily complicated?

So we are free to define any default behavior of selecting the compilation
buffer because any our decision will not affect typical users ;-)
