The word experimental does not scream “temporary”. It actually implies that it’s in alpha or beta, and that there may be bugs. It implies “hey, try this out!”. Not: “hey, try this out but also we might take it away very soon”
I know they wrote in their forum post that they don’t know if they were keeping it, but since I didn’t read it the first time around I didn’t know. Not used to having to dig through a forum post before upgrading.
