Describe the feature

I really love the combination of the framed corner strip and the colorful Antiblocks. Those are well to emphasize modern buildings or technical ones like Tron. Right now, I use them as safety lines in buildings and airplanes. Due lack of blockplace, I thought about some ideas:

1. More in-block variations for the corner strips

2. Multi-Placement in one block-place
   In Vanilla, it's possible to place a torch and an item frame in one block.
   To minimize the amount of framed blocks, could this also be a thing for those tricky blocks? (e.g. placing two framed slopes in one blockplace to receive an framed inner prism corner - i gave up finding a combination of framed slope horizontal, framed inner prism corner and framed slope vertical placed)

Thanks for reading!

1. I'm not quite sure what kind of shapes you are suggesting. Can you provide a simple drawing or staged in-game example of what you are looking for?
2. That's not actually multiple blocks being placed in the same space. The vanilla item frame is an entity and can only be placed in the same space as a torch because the torch is not considered a solid block that would prevent it. This doesn't work with a Framed Item Frame for example because that is actually a block and not an entity.

Since the issues author didn't pay any more attention to the corner strip feature, I think I can explain it a bit better what I'd want and what I think the author wanted.
In modpacks like GTNH, we can place multiple "strips" in the same block/face (given the screenshots below and "sampsas" world)

The item is from "Forge Microblocks". I'm not a dev mod myself, but I think it was the forge microblock's api itself that allowed this kind of behavior.
Anyway, using the Strip block fromframed blocks, we can have something similar but no quite equal, since we cannot place multiple strips in the same face like the previous screenshots.

So, is it possible to have something like this?

Implementing this is theoretically possible, I'm not sure whether it will actually happen though as it would require a few tradeoffs which I'm not really a fan of.
