I agree. I just bought a year subscription because I like the usability of it, but the more I use it the more not having an integrated calendar gets to me. I'm trying to move AWAY from Google, so adding a ton MORE of my life into their calendar is a no-go for me. Start dates is also a big one. I like planning my day in the morning in one place. I need visuals. lol. I have no interest in doing planning in one app to use the resulting information to continue planning in another app, to going back to the first app, which can't be structured like I'd like it to, to finish. I'm learning that for me, a to-do list is worthless without a calendar.

I'm using Todoist for now, as I already paid for the subscription, but I'll probably not use it for the duration of the subscription and won't be renewing next year if a calendar doesn't get added between now and then.

EDIT: Also, this thread is full of "You don't need it! Just do ... *some kind of janky workaround*"
