SWR: word for a regulation that relaxes something

The sentence is:

This implies there might be a certain degree of __________ for outbound flows.

I want to say "relaxation" but that sounds to evocative of sitting on the sofa watching tv kind of relaxation. Is there a better choice that has a similar meaning as relaxation but is implying a regulatory context?

Leeway. Merriam-Webster:

2 : an allowable margin of freedom or variation : tolerance

The new rules allow managers greater leeway in making decisions.

Leeway expresses the discretion a worker has, especially in the face of procedures, policies, or regulations.

This implies there might be a certain degree of leeway for outbound flows.
