Just remember to always add the required catch-all cases, lest you write a partial function.

When just unpacking lists, or other types whose structure absolutely will not change, this is fine.

When pattern matching on alternatives that might be added to, I find if I'm inspecting the values of existing cases I will probably want to also give consideration to how to handle future cases, so I avoid a catch-all (and make sure my tooling calls out inexhaustive matches) so these spots are surfaced when the type changes.
