It is. std.xml, std.json, std.stream...

The bar was raised in an effort to improve quality but it was 
done so at the expense of incremental improvements. I.e. it had 
to be near perfect or nothing. Given the size of the D community 
it is the latter and Phobos is effectively in maintenance mode.

If D had contributors lining up like say Python then it might be 
a different story but it doesn't.

I am only guessing but looking at the module I'd say the way it 
is structured doesn't fit in with "modern D", i.e. it isn't 
betterC friendly with @safe and @nogc, liberal use of @property 
etc.
