To be honest, I'm curious to know about this as well! Haven't read anything on this but I wonder at times how is the core Bitcoin team looking at what's happening with PoS and deciding "Nope. This tech is good for 200 more years". I guess time will tell. The inability to move / be more versatile is the reason why Ethereum came to be in the first place. I guess Bitcoin's main USP is "You can be sure Bitcoin will be Bitcoin as you know it for a long time". Also there's one section of the community that thinks Bitcoin mining will actually help move to greener tech faster since it incentivizes you do so.
