Yes, this works, and with rulethickness=0 it even looks like I wanted it to.

Hi, maybe you remember that I wanted this since 2017...
I finally managed to get a fuzzy background behind text:
"""
\setupbodyfont[ss,24pt]
\definecolor[tshade][t=.05,a=1,k=1]
\starttexdefinition MyCaption #1
\startMPcode{doublefun}
steps := 10 ;
rulesize := BodyFontSize/steps/3;
for step = 1 upto steps:
draw lmt_outline [
text = "\bf #1",
%style = "bold", % doesn’t work
kind = "both",
fillcolor = "white",
drawcolor = "tshade",
rulethickness = (step*rulesize),
];
endfor;
\stopMPcode
\stoptexdefinition
\starttext
\MyCaption{Eine wunderschöne Bildunterschrift}
\stoptext
"""
Remaining problems:
* lmt_outline doesn’t understand "style"; would be nice.
* I don’t understand why the white fill is not opaque.
