Its still around but is morphed a bit since then. At the 2000 AUSA Exposition, Boeing was showing a potential modification of the EKV that included a Jello spray. Yup, Jello. the idea was to pump the liquefied jello out to form a cloud which would coat the optics and solar panels of the target satellite. The effect of flash evaporation and solar radiation would be to turn the deposits into an opaque gel that would destroy the optics and cripple the power generation capability of the solar cells. I don't know if thats been pushed any further. The idea was to avoid the debris problem by keeping the target as a unitary but useless lump.
Back in Nike-Zeus days, the idea was to wrap the nuclear device in the warhead with gold foil. That, combined with a couple of other tricks, produced a relatively low "explosion" but a horrendous sleet of radiation that would have fried the target warheads. Thats one reason the idea of a nuclear interceptor went out - the initiation of the warheads would have fried every satellite in LEO (the effective range of a Zeus warhead against an unshielded satellite was in the region of 1,000 kilometers).
I don't believe a "nuclear shaped charge" is possible. By the way (and just out of interest), the device that destroyed Hiroshima was a Mark 1 and the one that got Nagasaki was a Model 1561. The devices intiated by Pakistan a couple of years back were reportedly analogues of Mark 1 but there is some doubt if the Pakistani ones worked at all. They may have fizzled.
