I think it’s an annoying, but I guess useful, reminder to the user that they have disabled their HT surrounds - a quick way around it of course, is to use LED ‘light dims’ (or just a bit of coloured tape) or even a piece of coloured paper to cover the lights. I do wonder if the LED’s were not showing, if it might lead to further support calls if people were to go onto forget they had disabled their surrounds. My own personal choice would be to leave the light showing, but perhaps not have it flashing, as it’s quite noticeable in a dark room - I would also prefer a darker red colour too, if that’s possible, as I would find that a little more night-friendly.

I do understand why it does it, however, there's already a feature for turning off the LEDs that the user has to actively turn on, implying intention. They could just extend it and make more granular. Turn on LED for: mute, connectivities issues, etc.
