Usage of missing apiVersion for Renderer is not detected

[flovogt]

Expected Behavior

Detect that renderer has no apiVersion set. Renderer has to use apiVersion >=2.

Current Behavior

ButtonRenderer.js:

sap.ui.define([
	"sap/ui/core/Renderer",
	"./BaseRenderer"
], (Renderer, BaseRenderer) => {
	"use strict";

	const ButtonRenderer = Renderer.extend(BaseRenderer);
	// The following line is required to be set to 2, UI5 linter should detect this and suggest to set it to 2,
	// otherwise the render method is not compliant with UI5 legacy-free
	// ButtonRenderer.apiVersion = 2;
	ButtonRenderer.render = (oRenderManager, oContainer) => {
		if (!oContainer.getReadyForRendering()) {
			BaseRenderer.render(oRenderManager, oContainer);
			return;
		}
	}
	return ButtonRenderer;
});

BaseRenderer.js:

sap.ui.define([], () => {
	"use strict";

	const BaseRenderer = {};
	BaseRenderer.apiVersion = 2;
	BaseRenderer.render = function () {
	};
	return BaseRenderer;
});
