Well, if there is no class that seems to make sense to group them, that's an additional flag that points to additional thoughts on design. Or discussion with fellow developer about it.
Of course, on some very exceptional case, 7 arguments might be relevant after all. If that is like the single one in the code base, and after thorough discussion with everyone implicated in the maintenance of the code it was agreed as an exceptionally acceptable trade-off for some reasons, making sure this would not leak in all the code base as it's called almost everywhere, then let it be.
But if it's a generalized style through the whole codebase, there are obvious lake of care for maintenability of the work and the team is going to pay for that sooner than later.
