I think I heard somewhere that this feature is back in iOS14, but I may have misremembered or misheard that.
But in any case, BART by @jim_sauer provides a workaround for this, and lots more besides, all in one tidy package. You can restore individual shortcuts using the Restore One option. It’s certainly my goto for offloading and restoring shortcuts and is how I manage all of my shortcut archives that I store in a GitHub reporistory (the Working Copy file provider is so useful).
