Qualify into trait

[matzipan]

I am not sure if this is the right way forward, but it's a temporary way to fix master:

Problem is that the problem does not exist on main. It seems that adding serde does some spooky action at a distance or did you implement any additional traits on Subsecond @matzipan?

I did not implement any such traits. It might be serde. I'll look into it a bit more.

I guess the solution that Angus suggested is a good way forward. I can make it part of my MR.
