Do you have plans to write some kind of migrate process plugin to migrate old D7 faqfield to the new D8? Since you've wisely moved away from Field Collections (and thus away from Paragraphs and entity references), is this something that is possible? Or would you advise some other method of migrating D7 content to D8?

I don't actually think the process plugin is needed at all. The mapping here is identical to what is was previously.
