Add option to set canonical_url to embed_url

Should this be a configurable? Is there a good reason for keeping the current behavior of always using the topic’s URL as canonical?

Yes. And by default don’t enable the blog post’s URL as canonical. Let the customer set the switch. Otherwise this is going to change a lot of Search referral traffic all of a sudden.

@gerhard

Should the blog post’s URL only be used as canonical for N pages presented to the search bot? After all, only a certain amount of posts is embedded in the blog post. (N probably should be 1)

IMHO, only the blog post linking top post should be made canonical. The responses and follow ups should not be.
