Will we ever get an Altar Level increase beyond level 4?

The new update came with an overhauled Fenrig's Farm - which they did a fantastic job with for the record!

My problem is though, this is where I've been building my town, and with the new terrain surrounding me I ended up with some harsh edges around my build area. I thought I could terraform within my build range to sort of bridge the gap, but there is a gap between my build area and the edge of the new terrain, so I can't actually fill it in. Will we ever get to expand the altar beyond level 4?

Would be slightly less upsetting if I knew I could fix it in the future.

(And yes, I know I can just use more altars! I plan to expand in at least one direction, but there will still be some gaps)


EDIT: So apparently if I temporarily place an altar near the gap, I can fill it in, remove the altar and it will stay on reload. Somehow. I don't understand how. But I'm happy!
