We do this as well, for example, when establishing names based on dissertations we will add $t under the assumption that earning the PhD signifies the end of that person's association with the Institute (though such is certainly not always the case).
But in the case I'm asking about I don't really know if 1984 or 2014 are beginnings or endings, or just points in a range.
So it seems that in these cases it would be most prudent just not to record the inferred date in the 37x at all? Unless, as John Marr suggests, a new MARC subfield should be established for the purpose (which seems unlikely to me, at this juncture).

Subject: Re: [PCCLIST] Question regarding use of $s in 37x fields
In authorities that I create, I have been giving just the $s or $t if that
is all that I know. I think a start date without a termination date is
still more information than nothing at all. It doesn't concern me that
the 373s might only each have a start date. I think more commonly I've
had a termination date for one affiliation, and the start date for the
next. That's also informative to record I think. E.g. (made up example):
373 University of Wyoming $t 2009 $2 naf
373 University of Oregon $s 2009 $2 naf

> In MARC authorities fields 370 (Associated place) and 373 (Associated group), as well as several of the other 37x fields, we have subfields defined to record dates of association--$s for beginning dates, and $t for end dates. But quite frequently I find that the information available to me does not tell me when exactly a given association began (or ended) but simply that it existed at a certain date.

> All of this information can, of course, be gleaned from existing 670s, so it's not like it's absolutely necessary to include in the 373; still, I was under the impression these new information fields were seen as useful for future linked data, etc., so it is useful to include a date range (or "date point") if possible.
