Leveling 50-60

I have several alts at level 50 following a break I took prior to 8.3 releasing. Do I need to go to the Shadowlands to effectively get them to 60 for Dragonflight? Or can I level them in BfA with world quests and other repeatable content there?

Chromie time has been extended to allow leveling 10-60 in any expansion except Dragon Flight.

Should be no problem leveling BfA to 60.
