no, unrelated, try this:

distance=0pt]
\define[2]\SectionCommand{\inleft{XX}}
That was fine until it ran into \setupwhitespace with a non-zero value.
Fiddling with the after key \blank does not appear to help.
\define[2]\MarginHead{\inmargin{#1\\#2}}

%setupwhitespace [none]%okay

you can always skip back whitespace or add 'nowhite'
Well, nowhite is a start, but the solution is still a way off.
Meanwhile, the following works for non-grid layouts with reasonable
values for \setupwhitespace, although perhaps somebody can come up with
a more eloquent way to write it:
\newdimen\SectionHeadSkip
\SectionHeadSkip\dimexpr-2\lineheight-\parskip\relax
\setuphead
[section]
[command=\SectionCommand,
distance=0pt,
after={\strut\blank[\the\SectionHeadSkip,samepage,disable,nowhite]},
]
\define[2]\SectionCommand
{\inmargin{#1 – #2}}
A better formulation (better because it preserves any stretch that might
defined by \setupwhitespace):
\setupwhitespace [big]
\newdimen\Parskip
\Parskip\dimexpr-\parskip\relax
\setuphead
[section]
[command=\SectionCommand,
distance=0pt,
after={\strut\blank[\the\Parskip,-2*line,
samepage,disable,nowhite]},
]
\define[2]\SectionCommand
{\inmargin{#1 – #2}}
As with the previous, \Parskip has to be redefined if \setupwhitespace
changes, so it is probably best left until after \starttext, when the
body font is established.
When enabling grid layouts, the number of lines needs to be adjusted.
No, it is not stable on grid layouts. Sections that have a figure placed
as the first thing will be a line off.
Floats that appear as the first thing after a heading may present
problems, especially with larger values for \setupwhitespace. (The
default, with no location= specified, is pretty good, but when
location={left,force} or such, there is often an unwanted offset from
the header. and page breaks still appear between the heading and figure
at times, despite the samepage setting for \blank.)
So, this is quite fragile. It requires careful checking of every
heading, and manual tuning when one breaks. Not a desirable solution,
but at least it is possible.
Still fragile.
