Long Term Part Time workers under a leasing/ temp arrangement

Is there information out there about how the long term part time rules inter play with leased employees? a plan sponsor uses a temp staffing agency for their workers and while most never work 1,000 hours in a year to ever meet regular eligibility,  there are probably a number that would be classified as LTPT under the SECURE 2.0 rules. 

Does the sponsor need to offer the plan to the LTPT workers? 

What if the doc excludes leased employees?

What if the doc doesn't exclude lease employees?

Is the answer different? 

Assume the staffing organization does not offer a retirement program. 

I don't think SECURE altered §414(n)(2) but I've been wrong before, so I figured it was worth it to ask since maybe someone else already figured all this out. 

If this has already been discussed, my apologies, please point to the thread and I'm happy to read it. If there are articles, presentations floating around out there that cover this particular point, please let me know as well. 

EDIT to add: what about common law employees? possible similar issues?
