What does the maintainer mean by that ... context can add profiles if 
configured to do so (best not to embed them) ... and why should there be 
a profile anyway ... crappy arguments .. especially because when i run

\usemodule[tikz]

\startTEXpage

\definecolor [colorone] [r=0,g=0,b=0.5]
\definecolor [colortwo] [c=0,m=1]

\starttikzpicture
     \fill [colorone] (0,0) circle(2) ; % rgb
     \fill [colortwo] (0,0) circle(1) ; % cmyk
\stoptikzpicture
\setupcolors[cmyk=no]
\starttikzpicture
     \fill [colorone] (0,0) circle(2) ; % rgb
     \fill [colortwo] (0,0) circle(1) ; % rgb
\stoptikzpicture

\stopTEXpage

here i get a pdf file with rgb and cmyk. Maybe I have an old tikz and 
something changed (wouldn't be the first time). So let's forget about 
maintainers and ugly hacks, and identify what is the real problem.
