Mandatory XKCD - https://xkcd.com/1172

We recently had a discussion about a similar "nobody we know uses nor
should use this api" situation in IPython, and ultimately decided that xkcd
1172 would hit us, so opted in this case just for creating new cleaner APIs
+ possibly doing slow deprecation of the old stuff.

For a widely used library, if the code exists then someone, somewhere
depends on it, regardless of how broken or obscure you think the feature
is. We just have to live with that.
