I think those numbers are from the last time I looked at the minimal
binary sizes which was probably around 2005 or so.. A lot more
functionality has been added over the last 18 years and there has not
really been much focus to trying to make sure the minimum size would
remain small..

I'm not sure which wording you are referring to here..  This 35-50 kB
reduction is from 2005 as well and at the time and this one is reduction
as it says while the numbers on the web site are for the full binary.

Well, I'm not sure whether there is really much interest on keeping this
type of number up-to-date and as such, that update might mean simply
deletion of any numbers or adding a note pointing out that the values
were from a snapshot in 2005 and do not indicated more or less anything
about the current snapshot.
