Still puzzling. I guess the ".sxref" files were updated because there
was a doc build (maybe for a planet package?) after `setup-plt -D'. But
then the files should have the right version. The ".sxref" files
really do start with the old version number, right?

I haven't yet managed to reproduce the problem. Does it happen with the
current Planet version of "fasttest.plt"?

".scrbl" files are compiled even if you supply -D, since -D currently
only controls rendering. Now that you mention it, though, ".scrbl"
files could be skipped when you supply -D, and I'll look into that
change.

In any case, I don't see why ".sxref" files would be needed when
compiling ".scrbl" files, unless some for-syntax module explicitly
loads cross-reference information (e.g., though `load-collections-xref'
from `setup/xref').
