should we make these slices with a higher capacity?

It's hard to predict how a user will use this. If they want a higher capacity they should just use the slice of Components directly

This looks unsafe.
last points to the last element in the slice. So appends to the first bit(the multiaddr) will modify last, right?

Perhaps not worth breaking this function, and it saves us some pain with updating downstream deps. For example, drand would not require a backport of this change to work with multiaddr.
The risk of then calling a method on the returned nil pointer is alleviated by changing the Component methods to be pointer receiver (as before) and checking for nil pointers explicitly.
Would also remove these breaking changes:
