Carefully avoiding terminal prepositions has been, for at least a generation, a dead letter. There are doubtless people my age who still practice it; but nobody except a few cranks think it a defensible ‘rule’. It survives in public consciousness largely because dogmatic ‘descriptivists’ enjoy using it as a stick to whack ‘prescriptivism’.
There are, to be sure, times when ending on a preposition is undesirable—for instance, if you want to end a sentence on a ringing call to action—but that's a musical consideration, not a grammatical one. And with particle verbs, where the particle-that-looks-like-a-preposition may be moved after the object, it’s a bad idea to move it so far away that the reader or hearer loses track of the connection.
