In most of the case when you want a custom cusor it’s the hand/link cursor. So you should continue to use a link block wrapper, as you want a link behind the cursor, right?
Use the new cursor feature mainly for interactions: when you need to unfold things, trigger click interactions, then use the new cursor feature, with the link cursor (hand).
There aren’t a lot of use case for the other cursors at the moment. Don’t go crazy using them or you will confuse your users like of they were in 1999 when cursor were animted, blinking, leaking rainbows… 
All of these aren’t really rules, rather common sense.
