As I wrote on the PR --

Introducing a new top-level package is a HUGE DEAL. For one 
thing, it will break build tools such as rdmd, which know which 
top-level packages to exclude from linking (as they'll be in 
phobos.lib). For another, it might conflict with users' packages.

We need a very strong reason to do this.

Also, what precedent does this set? If we start throwing 
image-processing code into Phobos, does that mean we should 
introduce another top-level package? Where do you draw the line?
