"Unique" is a very unique word

I have always used "unique" in a binary fashion, defining something that is the only one of its kind.  As such I have considered modifying adjectives to be inappropriate.  This morning I learn that I am apparently "behind the times."  Here's part of the entry at Merriam-Webster online:

1 : being the only one : sole
2 a : being without a like or equal : unequaled
2 b : distinctively characteristic : peculiar 
3 : unusual

usage Many commentators have objected to the comparison or modification (as by somewhat or very) of unique, often asserting that a thing is either unique or it is not. Objections are based chiefly on the assumption that unique has but a single absolute sense, an assumption contradicted by information readily available in a dictionary. Unique dates back to the 17th century but was little used until the end of the 18th when, according to the Oxford English Dictionary, it was reacquired from French. H. J. Todd entered it as a foreign word in his edition (1818) of Johnson's Dictionary, characterizing it as “affected and useless.” Around the middle of the 19th century it ceased to be considered foreign and came into considerable popular use. With popular use came a broadening of application beyond the original two meanings (here numbered 1 and 2a). In modern use both comparison and modification are widespread and standard but are confined to the extended senses 2b and 3. When sense 1 or sense 2a is intended, unique is used without qualifying modifiers.

And I can't resist adding: Q: How do you catch a unique rabbit?  A: Unique Up On It. And - Q: How Do You Catch A Tame Rabbit?  A: Tame Way, Unique Up On It.
