Lovely! This applies to ConTeXt's default font size of 12pt, doesn't
it? Hence we would have the following linear relation if the thickness
is 0.4pt at 10pt font size:
thickness = 0.4pt * fontsize/10pt.
Judging from the following:
---
\startuseMPgraphic{rule}
linecap := butt;
defaultrulethickness := 0.4pt*BodyFontSize/10pt;
path p;
p := origin--(EmWidth,0);
draw p withpen pencircle scaled defaultrulethickness;
\stopuseMPgraphic
\starttext
Lorem ipsum dolor sit amet
\startformula
\sum_{n=0}^\infty \frac{x^n}{n!}\!\vcenter{\useMPgraphic{rule}}
\stopformula
\setupbodyfont[32pt]
Lorem ipsum dolor sit amet
\startformula
\sum_{n=0}^\infty \frac{x^n}{n!}\!\vcenter{\useMPgraphic{rule}}
\stopformula
\setupbodyfont[72pt]
Lorem ipsum dolor sit amet
\startformula
\sum_{n=0}^\infty \frac{x^n}{n!}\!\vcenter{\useMPgraphic{rule}}
\stopformula

this seems to be true in general. (Hans, Taco, can you confirm this
officially?)
Could one perhaps pass "DefaultRuleThickness" on to MetaFun just as
the variables "BodyFontSize", "ExHeight" etc. are made available?
Best,
Oliver
