Comment 2 for bug 1849162

That makes sense. Maybe we could reconsider that decision?

Quoting an e-mail from a thunderbird developer:

« In the Thunderbird community there has been quite a few discussions lately on the problems with that packaging, especially regarding the Lightning calendar. Thunderbird upstream is shipping Lightning bundled and on by default, but apparently in Ubuntu an explicit install decision needs to be made by the user. This has caused major problems for users who couldn't figure out how to get lightning, or why it didn't show up in the first place. »

People who have used upstream builds of thunderbird will expect lightning to be bundled. At the very least we can bundle it in the main thunderbird package, maybe not enabled by default? That would mostly fix the discoverability problem.
