Hi Simon, excellent.I've been feeling and expressing this same idea. Feature of Interest should be an earth realm or a name place from a gazetteer, where we could infer the earth realm. Should not be a geometry, as Ron said.
But, my feeling is that when a domain scientists refer to a type of data ( trajectory, station, profile .. ) they are really referring to characteristics of the observing procedure ( in this case .. the constraint behavior of a sensor or platform ) which is confused sometimes with the feature of interest.

Actually I think the issue is that the domain scientists, quite reasonably, are used to working with some domain-assumptions. For example, when you are an atmospheric scientist talking to otheratmospheric scientists, the subject of your studies and observations isthe atmosphere. Doesn't need to be stated explicitly, or maybe is just inferred from the fact that elevation component of the location is >0. I'm comfortable with this. That's really why the SamplingFeature is useful. It allows you to work with a feature that is primarily defined by its shape for everyday purposes, without totally abandoning a rigorous model that recognises the fact that there is a domain featureunderneath, and it is really the domain feature that has the properties.To help with this, here's some "convenience" features, that you can use as the "feature of interest" of an observation, of the "sampled feature"of a sampling-feature ;-) <https://www.seegrid.csiro.au/twiki/bin/view/CGIModel/CGIFeatureRegister #Register_content>
