Splitting this question seems to have caused Craig’s Visualforce code example to get lost, so below is the whole post. Craig, I will look for information to help answer this.

I've read through this post and the lightning guide here: https://docs.skuid.com/latest/en/skuid/deploy/salesforce/using-skuid-lightning.html
What about page assignments? We have a customer with 10 different detail pages with page assignments showing 10 different Skuid pages. It looks like the custom lightning component you have to specify the Skuid page. How would we replicate the functionality of the VF component? i.e.:

<skuid:page objecttype="Account" actiontype="View" /> 

Craig, I’ve found that enabling page assignments with Skuid on Lightning is on our development roadmap for a future release. We’ve noted this Community post in that dev story, and we will update this post when the functionality has been tested and made available.

Great, thank you. For now, I will advise clients to stick with classic to use page assignments. 

Thanks Mark.
