Although anything that doesn't implement 5011 should already be
experiencing problems since KSK-2010 is no longer being used to sign
anything.  Any of those systems that are not experiencing problems now must
have had their trust anchor manually updated, and revocation or removal of
KSK-2010 should be irrelevant to them.  I would expect the only problems to
be exposed by revocation or removal of KSK-2010 to be bugs in 5011
implementations.
