No, I mean't there's code in the IDL:

$ grep "\->" *
epmapper.idl:		[value(ndr_size_epm_towers(&r->towers))] uint32 
eventlog.idl:		[value(2*strlen_m(r->name))] uint16 name_len;
eventlog.idl:		[value(r->name_len)]       uint16 name_size;
lsa.idl:		[value(2*strlen_m(r->name))] uint16 name_len;
lsa.idl:		[value(r->name_len)] uint16 name_size;
misc.idl:	/* security_descriptor->type bits */
netlogon.idl:		[value(strlen_m(r->string)*2)]  uint16 size;
netlogon.idl:		[value(r->size)]                uint16 length;
netlogon.idl:		[value(r->length)] uint16 size;
samr.idl:		[value(ndr_size_security_descriptor(r->sd))] uint32 sd_size;
samr.idl:		[value(2*strlen_m(r->name))] uint16 name_len;
samr.idl:		[value(r->name_len)] uint16 name_size;
samr.idl:		[value(strlen_m(r->name))] uint16 name_len;
samr.idl:		[value(strlen_m(r->name))] uint16 name_size;
winreg.idl:		[value(strlen_m_term(r->name)*2)] uint16 name_len;
winreg.idl:		[value(r->name_len)]              uint16 name_size;

Well you can use transmit_as and basically bypass the usual encoding
entirely. I'm not surprised. Somebody could have just punted on
IDL-izing and memcpy'd instead maybe.
