That would mean we’d avoid the tikz module, every TikZ diagram will get written to a buffer of configurable name, and that (with preamble setup) will get run through LaTeX. I read pgf had some restrictions in plain TeX mode, but perhaps we can also use LuaTeX in plain mode to avoid the LaTeX dependency.

It is not only the tikz setup; you also need to copy the font setup etc.
\typesetbuffer[setups,figure]
or some variant of that should also work. But the filter module does make it easier to store the results in another directory so that they are out of sight.

Here is a simple example:
\usemodule[filter]
\startbuffer[tikz-before]
\usemodule[tikz]
\startTEXpage
\starttikzpicture
\stopbuffer
\startbuffer[tikz-after]
\stoptikzpicture
\stopTEXpage
\stopbuffer
\defineexternalfilter
[externaltikz]
[
bufferbefore=tikz-before,
bufferafter=tikz-after,
cache=yes,
filtercommand={context --batchmode \externalfilterinputfile\space --purgeall --result=\externalfilteroutputfile},
output={\externalfilterbasefile.pdf},
readcommand=\readPDFfile,
]
\define[1]\readPDFfile{\externalfigure[#1]} % width and height could be added
\starttext
\startexternaltikz
\draw (0,0) -- (1,1);
\stopexternaltikz
\stoptext
