Using Less preprocessor

When you use inheritance in Less, for example this code:

.block {
  margin: 10px 5px;
  padding: 2px;
}

p {
  .block; /* Inherit styles from '.block' */
  border: 1px solid #EEE;
}
ul, ol {
  .block; /* Inherit styles from '.block' */
  color: #333;
  text-transform: uppercase;
}

it is compiled to

.block {
  margin: 10px 5px;
  padding: 2px;
}
p {
  margin: 10px 5px;
  padding: 2px;
  border: 1px solid #EEE;
}
ul,
ol {
  margin: 10px 5px;
  padding: 2px;
  color: #333;
  text-transform: uppercase;
}

What I want to ask, is it OK, to upload such .css file in wordpress.org themes directory? Would it pass a review? Cause it duplicates properties.
