It's not just in the PDF though, I can also see the change from Lua.
Using this document:

local i = 1
for n in node.traverse(node.tail(last_line.list), true) do
print(n)
if n.id == node.id("glue") then
print(node.effectiveglue(n, last_line) / 65536)
elseif n.width then
print(n.width / 65536)
end
if i >= 6 then
break
else
i = i + 1
end
end
return head
end

A, B, and D all have almost the same \parfillskip widths, and the exact
same "." and "o" widths. But comparing A/B/D to C, there's a 6.6pt
difference in the \parfillskip values and a 0.12pt difference between
the "o" widths.
Maybe it's just a coincidence, but it seems odd that enabling expansion
makes no difference with the latest version (A/B) and that latest with
no expansion (A) gives identical results to the old version with
expansion (D). Plus, a 6.6pt difference in glue lengths seems like a lot
for an accuracy change.
I could very easily be wrong here, but something seems off to me.

Re: [NTG-context] thousand separator space
Hi Jan,
> Why is there an additional space after the thousand separator in math mode?
Because something like
${\mathbb N} = \{1,2,3,4,\dots\}$
would look quite bad without any space between the numbers.
(The technical reason is that commas have the math class \mathpunct,
meaning that TeX automatically adds a space after them. Adding the
braces converts it to \mathord, which doesn't add any spaces.)
> And what can I do to get rid of the additional space?
The TeXbook recommends that you wrap the comma in curly braces
$x = 1{,}000$
but there's probably a ConTeXt \setupxxx command that would have the same
effect.
Many European languages use the comma as a decimal separator, so I'd
generally recommend using a thinspace (\,) instead of a comma as a
thousands separator to avoid confusion.
Thanks,

Replying to myself, and sorry for the noise (this was fairly easy,

instead of loading the file "examples.xml," I simply include it via
xmlinclude into the tree; this way the proper setups are applied.
