Thanks. In what sense are they unnecessary? For example, ssl.h requires
x509.h because ssl.h uses STACK_OF(X509) which is declared in x509.h:

x509/x509.h:151:DECLARE_STACK_OF(X509)

so it should include it directly.

While I agree with some of the other changes, the problem with committing
such a diff is that applications might rely on such implicit inclusions
and thus fail to compile. For example, err.h used to depend on lhash and
it is difficult to know whether some application out there relied on that.

So the cost of doing this might well outweigh the benefit.
