There is a real trend to purify the language. I also think it's the
right decision to replace compiler intrinsics / language feature with
their library counterparts. Moving stuff to phobos is fine as long as
you use phobos. But I'm using tango and druntime. I haven't even
installed phobos on my system. The same impacts deimos. People tend to
create unneccessary phobos dependencys.
