I did a bit of archeology, and it looks like this was BMT (Before My
Time). But looking at the code, I *think* this may have been related
to the fact that we decode the value and store it in host-side format,
and it looks like the code is trying to find the best target-side type
match so as to avoid having to deal with too much precision if the host
isn't capable of it in the first place??? As you say, this might be
questionable, just trying to think the reasons behind it.

In any case, I looked at your changes, and they seem fine to me.
In fact, I welcome the simplification ;-).
