Most of the time, when people use "private", they are actually
shooting their users which can't even extend their class. I
rarely see code which people use "protected" instead and I find
that pretty lacking. One thing is hiding memory allocation
details on your class, other thing is hiding a property which
could and should be controlled when extended in a class.
To be fair I'm more often than not against private variables.
Most of the time it only caused me headaches because there was a
lot of unimplemented features and I could not simply fork the
project. This is not only in D. I got that in Java, Haxe, C#.
Thankfully those languages has ways to simply ignore the private
attribute, which can't be done in D.
Anyway, I'm not against static classes and I don't think they
would bring any inherent problems, they should not cause
regression and they should be easy to implement as the compiler
already has the tools for it
