>Exile it at the beginning of the next end step or if it would leave the battlefield [the latter half is redundant with it being a token].

It's not necessarily redundant or useless, there are some cards that will trigger off exiling permanents, or count the number of permanents that have been exiled during the turn to change how powerful an ability is, so if it was destroyed in battle or kill-spelled and instead exiled, it would be more useful than it simply being destroyed unexiled since it would trigger the ability or increase the count of permanents exiled that turn.

Oh, that makes sense. It doesn't technically exile when it's removed from the battlefield; there's just nothing to come back.

Thanks for the clarification!

To explain my position a bit more, I was considering, e.g., Restoration Angel but that's still moot with your point.

Not quite, it actually does fully exile, and even exists very briefly in the exile zone, but then fizzles once state based actions are checked again, which is usually very quickly.
