Hi @oanguin, if you look at the PR, then you will see that @sdf611097 was asked for input over 7 months ago and still hasn't replied.

If you'd like this feature, I'd suggest working on the PR or submitting your own PR.

The key thing lacking from the PR was testing and evidence that it didn't introduce breakage.

Hope that helps,

Alex
