No, actually it wouldn't.
Whether it's a good idea depends on what you are transplanting over it.
Probably not a good idea for cabbage. Much better for pumpkins.
The one and only way I was ever able to grow edible melons up here was
to dig a trench about 14 inches deep, fill it almost level full of very
fresh horse manure and then put the soil I dug out, back on top. This
created a raised bed where I placed melon transplants. Two days later, a
soil thermometer stuck into the raised bed was 15 to 20 degrees warmer
than soil a few feet away. I also covered the ridge with black plastic
(before the plants went in), which was a part of why the raised bed was
warmer.
With both watermelon and muskmelon, the difference is like day and
night. Ten times as much vine growth in our cool climate.
