no
Is it possible to render text as paths not as referenced glyphs in
MetaPost/ConTexT?
no, unless you use the graphic text features
Unfortunately I have to stick to SVG as the resulting output format.
Converting from PDF to SVG is not an option at the moment due a)
performance considerations and b) trouble with generated font names in
the resulting ConTeXt PDF file (inkscape as well as pdf2svg produce real
strange results).
performance should not really be an issue as one can cache
what strange results?

Yes, Thanks.
I thought of this as a work-around, but the first is clearly a bug.
iirc, Hans says this is an intentional difference between mkii and mkiv,
but it is not yet on the wiki page because I am not sure what to write
down.

What actually works is:

for i = 0 upto 10 :
%draw thelabel(decimal i, (i, 0) scaled 1cm) withcolor red ;
