LFS is a reliable medium if it hasn't been long watered with hard water (something garden centers are notorious for). If the plant is growing well, my inclination is to let it be. Even if it contradicts standard advice. There are so many considerations, it's hard to tell what variable may or may not be affecting the plants growth. My rule of thumb is if it ain't broke don't fix it, but be aware of potential problems, be observant, and act if it seems the plant is somehow declining in health.
I have this moss as well as about 30 others. As far as being a detriment in and of itself, it is fairly well behaved: a slower growing moss. The worst is a low flat growing long moss that is impossible to eradicate even going to bare root. It always returns around the base of the rosettes, making transplants mandatory twice a year, or else the plants will be buried.
My greatest success comes from using seasoned peat/sand that has sat in the rain for a season premixed in pots. These pots rarely get any moss growth.
