What happened to the '-x' option of dcopy(1M) ???

What would be the PURPOSE of forcing executables to be
stored contiguously?  This *could* reduce drive seeking if
accesses against the particular filesystem tend to group
in time with type (i.e. executable, non-executable).
In the case of mixed programs and their data on the same
filesystem and assuming that data i/o exceeds initial
text load the benefit from the '-x' option would be from
having the *non-executables* (data files) contiguous.
I see no benefit on systems where "program data" is localized
in its own filesystem(s).

I am attracted by the idea of keeping file system code clean
of garbage collection routines and have had good experiences
with dcopy(1M).
