Why? Cross platform encryption is solved in a myriad of ways. Only thing missing is consensus and key verification. I think apps live Threema show how it can be done. Lacking a central instance to bless keys one could verify in person by scanning some code.
I wonder how the cross messaging between apps will work. Especially when you think about encryption.
The IETF recently adopted a standard on E2E encryption. Perhaps the law will mandate the implementation of MLS.

(there is also a quite good article on a German IT magazine, maybe check this out using DeepL)
