Yes, for both MkII and MkIV. But this still does not fit the requirement
of my module.

\setupexternalfilters
[directory=,
outputfile=~/output/\externalfilterinputfile.tex,

will fail. (The above will generate all the *-*.tmp files in current
directory, which can be purged by passing --purge. The output files are
generated in ~/output directory for future reference. But \ReadFilter
cannot read the file.

I think that I will go with separate definitions for MkII and MkIV, or
perhaps even redefine \ReadFile just before the read function is defined.

IIRC, system modes cannot be reset using \(enable|disable)mode.
