Let's answer another question from you.
Q: Are you planning Thunderbird integration with Telegram? For in-app chat, or for using as attachment storage?
A: Not right now, because Telegram is closed source on the server side. We want to focus on decentralized, open standard solutions.
To use it as attachment storage, anyone could write a cloud file extension: https://webextension-api.thunderbird.net/en/latest/cloudFile.html
Here are some existing solutions using services like Dropbox and Nextcloud: https://addons.thunderbird.net/search/?q=filelink

2nd this! At least for the encryption compatibility. DC doesn't really "require" a chat style UX, (email works with any UI design) but a UI option that enables that style is definitely welcome.
