This is excellent news!

I think one can formulate it in this way.

Once I reversed the design, that is, letting continuation frames to hold the tip of the current dynamic environment chain and simply restore it when popped, things seem to become a lot simpler.

It is good to hear that it simplifies things because this is how new
features for Scheme should behave if possible.
