Any details on the support for Toyota's Entune 2 system?

I just bought a Toyota Tacoma 2019 that has the Entune 2.0 system.  I have seen a lot of questions about Spotify support but looking to see if there is a reason why this cannot be supported.  If it's just a development cycles issues I am sure that there are enough people in the community that contribute development cycles to make this happen but guessing it's a contractual issue of some sort.
