Ah, right; I forgot about that.

On the other hand, the required code is three lines:

(defclass xref-ada-backend (xref-backend-class) ())
(defvar xref--ada-backend (make-instance 'xref-ada-backend))
(defun xref-ada-backend-function () xref--ada-backend)

xref could provide a macro that does this.

Everything else in a major-mode backend can be non-EIEIO.

Perhaps I've misunderstood what you are proposing.

I have the impression you are proposing to entirely delete EIEIO from xref.

What are you proposing?
