If you mean you can step them upward in 1/4th increments, you could always do that without fence foundations. Any wall-like piece or regular fence piece placed atop the edge of a foundation will let you snap another foundation to the side 1/4 higher.

What fence foundations previously allowed you to do was snap a second foundation 1/8th lower. In addition to the fine tuning advantages, a 1/8th difference is also the height that allows you to use foundations as stairs, whereas a 1/4th gap requires jumping. A 1/8th downward step also lets you fit ramps flush with foundations instead of having that ugly lip sticking out on top. There’s a bunch of little features like that in jeopardy if this stays as it is.

And being able to lower the piece was a huge time saver. Now if this isn’t changed what we’re going to have to do is use the 1/4 technique 3 times to reach 3/4ths higher, then build 1 sideways, 2 downwards, and 1 sideways again to get back to the original spot 1/4th lower. It’s a bigger hassle than corner pillars.

To top it all off, it’s still possible to run fence foundations through the middle of wedge foundations. Unless wedge thickness doesn’t matter in the explosives meta, this change hasn’t fixed anything.
