Why?  Is it just the bulk lead capacitance, or is there some other way
in which a DIP package is electrically deficient?

Bigger, yes.  Slower, I can't see why, unless it's bulk capacitance.
RoHS compliant, that's a historical accident rather than anything
inherent in DIPs, isn't it?  I can't see any reason why a DIP couldn't
be made as cleanly and compliantly as the corresponding surface-mount
part.
