The expressions are all evaluated in parallel to increase performance. This means each expression must be valid on its own.

This is intended. We do more work than needed, but we can do it in parallel.
You're seeing an error due to this change:
#16841
Add null_on_oob=True
to your get
calls and you won't see an error anymore.

If we count cpu cycles we don't do more work than needed. This allows us to vectorize the expressions. If we would execute them concurrently this would be super branchy and not very optimizable.
