I wonder just how much of a problem lead bearing solder used in

electronic devices is ...

Tin and lead is a stable compound, and the lead does not wash out of it
in

water. Pure lead is not soluble in water.

Not in pure water, maybe, but organic acids (acetic acid) attack lead
and you can't have decomposition of organics in contact with lead in a
landfill,
without some leaching.

Which goes nowhere at all. Landfills are lined with very thick clay
layers, and even if they weren't, heavy metals don't go anywhere in ground
water at earth-surface normal temperatures. See the Oklo natural reactor
in Gabon. It was sitting right there in an aquifer, and operated on and
off for half a million years. The fission products went something like 1
mile in well over 1 billion years.

The ROHS rationale was to protect the health of folks doing recycling. To
save some gloves and respirators, they created a monster. Typical
Eurocrat BS.
