It's hard to get excited about this. Per the IANA TZ data,
nowhere in the world has used fractional-minute UT offsets
since 1972:
# In 1972 Liberia was the last country to switch from a UT offset
# that was not a multiple of 15 or 20 minutes.
and they were twenty years later than the next-to-last place (although
IANA will steadfastly deny reliability for their TZ data before 1970).
So timestamps like this simply don't exist in the wild.

Perhaps that should be fixed, but it's pretty low-priority IMO.
I doubt there is any standard saying that JSON timestamps need
to be able to include that.

I'd vote no. to_date/to_char already have enough trouble with format
strings being squishier than one might expect.
