I've been using the Ancestry Share feature quite a bit over the last two years and my experience has consistently been that sharing an Ancestry Record doesn't provide any useful detail information (just the fact that a record exists for an individual in the collection and the name of the Ancestry subscriber that shared it). So I don't believe that anything has changed recently regarding sharing an Ancestry Record.
Sharing an Ancestry Image allows non-subscribers to view the image. So when an Ancestry Image is available, I use the share feature and include the Ancestry Sharing link (via the template) with the full citation of the source.
I also usually include in the citation any original associated Ancestry (subscription-required) Record and Image links (via the templates), as those links can be beneficial for subscribers to navigate to related or nearby records in the same or other collections.
I also usually add an abstract of the pertinent information from the record/image, which can be beneficial for non-subscribers, for English-language translations of records/images in other languages, and for when the links all eventually break.
But I'm not an Ancestry subscriber at the moment.
