What major implication did the existence of Hot Jupiters have for the core accretion theory as it was understood then?

Answer

It contradicted the requirement that giant planets form far from the star where disk material is abundant.

The presence of Jupiter-sized planets so close to their stars contradicted the theory because the heat and stellar wind were expected to have stripped away the necessary protoplanetary disk material needed for their formation before they achieved critical mass.
