Only you know how many HDCP 2.2 devices you are going to have. Keep in mind we are moving to an online/streaming model so 1-2 devices will be all that's needed. And many times one of the devices is the (smart) TV itself. Not too long ago we used to have CD players, VCRs, DVD players, Bluray players, HTPCs all attached to the AVR so you needed to have lots of inputs, composite, component, HDMI, ... conversions between all these, etc. I only speak for myself, but I haven't turned on the Bluray player in over a year, I'm not even sure it's still functional anymore. I'm redoing my setup and I'm not even going to hook it up. I will also look to donate my CD/DVD/Bluray collection as I haven't played any in a long time from the spinning media, they are all on a NAS now. So in my case all I need is a single input, a streaming box, currently the Fire TV 4K.
