Since #13515 non-zero exit status of a command on a trailing pipeline position errors. The same isn't true for pipeline elements.

So a) will error, while b) will not.
Assuming that b) doesn't collect its input.

# a)
foo | may-fail
# b)
foo | may-fail | bar

Describe the solution you'd like

According to @IanManske, changing that isn't possible with the current code structure

I still wanted to open an issue, since this might change at some point. If it does, I would appreciate it if nushell would error for both scenarios a) and b)
