Views won't list view mode of paragraph revision.

Problem/Motivation

I suspect this is partially a bug report and partially a feature request.

I have a view of paragraphs which Shows the output as Paragraphs using one of its view modes. I am not migrating the content type to use Workflows and therefore need to show revisions of these paragraphs. There are 2 approaches i can think of for this:

1. use the same Paragraphs view i have been using but use contextual filters to select specific revision of the paragraph. This does not work as the sql created for this is incorrect. This is possibly the same reason i can do this approach for views using Node content.

2. instead, i need to use a Paragraph revision view. This allows me to enter paragraph id and revision id. Perfect. Except.. there is now no option to show paragraph entities, only Fields. There is also no "entity" field as there is with nodes.

My other option is to put all the fields together and clone-ish the template i use for the paragraph view mode into a views field template. Possible, but i have a few of these to do and would seem to make sense that this supported Paragraph entity as a View formatter.
