Given the previously‐stated intention of making this default
for the 0.27 release, prepare for that decision ahead of time by
enabling subprocessing by default on trunk. This will help surface
any regressions and workflow incompatibilities and therefore give
us more information to decide whether to keep or revert this commit,
without inconveniencing any users who haven’t already opted in to
the bleeding edge.
Please feel free to revert without hesitation if any major issues
arise; this is not intended as a strong commitment to enable this
option for the next stable release if it turns out to not be ready. In
that case, it’s better that we learn that early on in the cycle,
rather than having to revert at the last minute or, worse, cutting
a stable release that we later find contains a serious regression.
