Date class shows Inf as NA; this confuses the use of is.na()
...real numbers working either, and doubles have that behavior generally. It
might be possible to put checks in (with a potentially non-trivial overhead
cost) to disallow that kind of thing, but again R (and everyone else, I
think?) doesn't do so for regular doubles.
Also, I would expect the year 1e50 and the "year" Inf to be functionally
equivalent in meaning (and largely meaningless) in context.

This looks somewhat reasonable as a workaround for you and for now.
However, I'd propose another route to go for "the next version of R":
When I consider
