The 1.6.3 bit probably comes from the version of the API that D exposes, as seen here: https://github.com/freebsd/freebsd/blob/master/cddl/contrib/opensolaris/lib/libdtrace/common/dt_open.c#L137. Adding new things should probably be done in the latest version i.e. 1.13 -- but I may be wrong (this is mainly by skimming the dt_pragma.c code to see what "binding" does.
Makes sense, thanks for the explanation and the link!
