Expected / Desired Behavior / Question

Standard SharePoint list forms implement Comments functionality. This functionality is required for our implementation for collaboration on tasks and issues.
Ideally, I would like to inject simple customizations into standard SharePoint forms, similar to injecting JSLink in classic forms. However, no such functionality exists in modern forms. For example, I need to set default value of the Org Unit field from a URL parameter value and make the field read only. Now, the only way we can implement it is with SPFx or Power Apps. Both options are an overkill and a deployment and maintenance nightmare. If there was a site collection feature to enable custom JavaScript injections, that would address a myriad of challenges.

Observed Behavior

Comments functionality is missing from Dynamic Forms component.

Steps to Reproduce

Implement Form Customizer extensions with a Dynamic Form for a list. Notice that Comments panel and show/hide button is missing from the form. Also, Comments option on the list item opens the Dynamic Form with missing comments controls.

Start with the Dynamic Forms component used by the Form Customizer extension and trace how a list item form is opened from the list item's Comments option. Done means the form includes the Comments panel and its show/hide control, with comments functionality available when the component is used for a list.
