Which was fixed 16 years ago with OpenPGP (RFC-2440).  OpenPGP actually
provide a superset of the features you require to implement the X.509
model.  It does not demand its use as it also does not demand the use of
the WoT or any other key validation model - this is all left to the
implementation.  Both major implementations support the hierarchical
model.
