I've seen discussions on buffered ranges, std.parallelism, replacement
of std.xml, std.process and std.stream and probably several other things
I've already forgotten.
DMD seems to have a quite updated roadmap in the wiki:

Does something like this exist for Phobos too?
The page above mentions Phobos, but only that it's a moving target.
There is no Phobos roadmap at this point. It's all very adhoc at this point.
There are plans for stuff to be replaced or added
