Thunderbird needs to allocate some resources for implementing #OMEMO for #XMPP. It's honestly a higher priority in my book than perfecting their #Matrix implementation.

XMPP is a rich protocol and the OG secure chat standard by which Matrix is inspired. It also has a massive usage proportional to other methods but the adoption is largely silent due to the federated nature of the protocol and the attitudes of the users.
