A reasonable approach to a Context file includes preliminary information before
the first printed page. My basic master file looks like this :
\input variables.tex\relax
\input layout.tex\relax
\input macros.tex\relax
\input fonts.tex\relax
\starttext\relax
%\showlayout
\startfrontmatter
\input half.tex\relax
\startstandardmakeup
\null
\stopstandardmakeup
\input title.tex\relax
\input copy.tex\relax
\input ded.tex\relax
\input contents.tex\relax
\input preface.tex\relax
%\startstandardmakeup \relax
%\null \relax
%\stopstandardmakeup \relax
\stopfrontmatter
\startbodymatter
\input body3.tex\relax
\stopbodymatter\relax
\startbackmatter\relax
\input bib.tex\relax
\input notes.tex
\input index.tex
\stopbackmatter
\stoptext\relax
By loading my usual macros in the macros file, standard items like author's
name in a variables file and so on I save much time,
typing and errors.

Hi all,
doing some tests I discovered two interesting facts.
The first is that commands \starttext and \stoptext do not behave as a group.
Minimal example (tested on TL2015, TL2016, TL2017, current CTX from the Garden):
\starttext
text
\starttext
\bf text
\stoptext
text % this text is in bold, too.
\stoptext
Is this the expected behaviour, or not?
Opening a group with \starttext makes no sense because there is nothing after
\stoptext.
The possibility to nest \starttext is necessary when you \startproduct etc.
where components
can be be documents on its own and this means \startcomponent includes
\starttext in its
definition.
The second interesting thing is that the unbalanced document is compiled
without protests:
Minimal example #1 (tested on TL2015, TL2016, TL2017, current CTX from the
Garden):
\starttext
text % in this case, the "text" is shipped out
Take a look at the command line when you process a file and you should see
something like this:
mtx-context | run 1: luatex --fmt="[...]/cont-en" --jobname="test" [...]
--c:input="./test.tex" [...] "cont-yes.mkiv"
As you can see the luatex engine processes the file cont-yes.mkiv and not your
document
which put as argument to context. Your document is just read by cont-yes.mkiv
and at the
end of the document ConTeXt inserts an extra \stoptext which is ignored when
your document
is valid (equal number of \starttext and \stoptext).
Minimal example #2 (tested on TL2015, TL2016, TL2017, current CTX from the
Garden):
text % in this case, the "text" is not shipped out
\stoptext
The reason why no text appears is that ConTeXt doesn't load the default fonts
untill \starttext. The reason for this is to is a gain in speed and you save
resources.
You can test this by adding \setupbodyfont[modern] at the begin of your example.
