placing mates in context

Is it bad practice to place mates in-context that depends on the ghosted part?
Will it create a circular reference or does it suffice to avoid updating?

One situation I can think of would be to offset off some unusual geometry that would be easier to locate with sketches or custom feature scripts to triangulate a point inside an assembly of parts. Rather than calculating and manually entering offsets in an assembly mate, or a pair of assembly mates each update. Like from the center of mass of a large machine. (although even that isn't difficult to update with a single mate, but you get what I'm laying down right 😉)
Otherwise, it won't do any harm or damage to your model. In-context is just easy to miss when updating. especially when other people are involved. It is best to keep in-context to a minimum, just for the sake of sanity.
Furthermore a student/physiotherapist or user should be able to study the basics of design and go in and improve the model (and unfortunately Onshape keeps failing on that point but currently I cant find a better alternative).
Therefore I strive to develop a workflow that allow us to guide new designers (and non) to develop parametric solutions. I've studied lots of beautiful solutions proposed by designers, usually they don't scale well or engineers who make perfect parametric solutions but they often involves incomprehensible steps.
Ideally it's should be so easy that you only have one tab to open and a few measures to insert - go to another tab see the functional model - 3 tab allows you to export a slicing ready model.
