I'm not sure about sheep pastures (no experience there), but wrecking yards,
repair shops and auctions (which is where the wrecking yards get the burn
jobs) I'm extremely familiar with, and I haven't seen a burn job with an
ignited engine case in years.

I even talked with my Father about it and he says that he can't remember the
last time he saw a burnt air-cooled VW where the case ignited.  And he's a
German born, VW factory trained mechanic that has owned repair shops in
SoCal since the '60s.  Pretty reliable info source.

More cheers,

I don't want flames so I'll qualify my statement about magnesium ignition in
the engines. Every burn job I've seen was in a wrecking yard, not in any
shop for repairs.
The one exception was in a pasture full of sheep.
