Is the latest version of Thunderbird truly not compatible with OSX 10.14 (Mojave) or has the website just not been updated yet?
Are there any plans to add compatibility to 10.14 and later?

I would guess the web site has just missed an update.
Looks like the Firefox folk have simply stopped publishing minimums. I guess the installer tells people if it is not a suitable version.
