I like the idea to keep some of it. It's a natural phenomena that you should have. But, if it covers most of the pond, I can see the need to remove a portion of it. As a matter of fact, that's what Bruce Kania biomimics when he uses his floating islands.
A floating bog and the plants on it absorbs and use nutrients from the water. They play a role cleansing water.
As far as "how" to remove it, I expect half a day's worth of excavator would do the job. The problem will be trying to schedule an excavator for only half a day.
