Still possible to retain Mojave-format reminders in iOS 14?

Any idea whether iOS 14 allows you to keep using the old (Mojave-compatible/iOS 12) reminders format, like iOS 13 did?

My Mac is still on Mojave, so never updated the reminder format in iOS 13.

I will update to Big Sur eventually but don’t want to install iOS 14 and have reminders suddenly no longer sync between phone and Mac.
