Hey @remyd1. Sorry for the inconvenience. We made a conscious decision to remove this behavior. Please see #1053 for the justification. Ping @olifre and @vsoch who were also part of that discussion.

Since we have already hashed this out in detail, I am going to close this issue. But feel free to keep on discussing. And if there is anything that can not be solved by placing the variable definitions in %post feel free to re-open. Thanks!
