Is this a bug, or just a change in setuphead that I didn't take
account of?
It is a bug. ConTeXt sometimes uses the rightmargindistance for the
left margin, which would be correct for a double sided layout, but
is definitely wrong for a single sided document. However, even in a
double sided layout the calculations are not correct. Here a smaller
example. Note that the output is wrong either way, with
\setuppagenumbering commented out or not.
%% \setuppagenumbering[alternative=doublesided]
\setuplayout[rightmargindistance=1cm]
\setuphead[section][alternative=inmargin]
\showframe
\starttext
   \dorecurse{16}{\section{Blah}
     \input tufte}
\stoptext
\startsetups[\??headrenderings:\v!inmargin]
     \vbox {
         \headsetupspacing
         \begstrut
         \dontleavehmode
         \ifconditional\headshownumber
             \llap {
                 \signalrightpage
                 \hbox {
                     \hfill
                     \headnumbercontent
                     \doifrightpageelse {
                         \scratchdistance\leftmargindistance
                     } {
                         \scratchdistance\rightmargindistance
                     }
 
\hskip\dimexpr\d_strc_rendering_local_leftoffset+\scratchdistance\relax
                 }
             }
         \fi
         \headtextcontent
     }
\stopsetups
