Technically, as is illustrated in the following document, trupets are considered substandard for freeway to freeway connections in Ontario. So, it shouldn't be too surprising they are building directional interchanges.

I'd say any freeway-freeway interchange with loop ramps is substandard.
Since we're talking about the 407, I think it's crazy how small the loop diameter is on some of the main 407-ETR interchanges. I recall all the 400-series ones were supposed to be stacks, but they were re-designed at the eleventh hour to save money. Hope this doesn't happen to 407 East.
