The reason rigctld emulation is a bad idea is that it changes over time.? And the client may want vfo mode or not so most every command has to be checked for VFO.
A rig definition never changes -- but it can be extended.
Historically rigctld emulation was only necessary if you wanted a socket connection but that's not true anymore.
You can connect to any rig via a TCP socket and in 4.7 you'll be able to have a UDP/Multicast connection to control the rig.

So here's a rigctld emulation in code.

fgets(buf,sizeof(buf),fp);
char vfo[16];
long freqA,freqB;
int n = sscanf(buf,"f %s %ld", vfo, &freq);
if (n == 2) { // then there's no VFO
????int n = sscanf(buf,"f? %ld", &freq);
? ? vfo = current_vfo;? // you have to track which vfo is active -- PITA
}
if (vfo == 'VFOA') freqA = freq;
else if (vfo == 'VFOB') freqB = freq;
else printf("unknown vfo")
printf ("read freq %ld from vfo %s\n", freq, vfo);

And here's a TS-2000 emulator which is very straightforward and easy to understand.

fgets(buf,sizeof(buf),fp);
char vfo[16];
long freq;
int n = sscanf(buf,"FA%d",&freq);
printf ("read freq %ld from vfo %s\n", freq, vfo);
if (n == 1)
{
?freqA = freq;
}
n = sscanf(buf,"FB%d",&freq);
if (n == 1)
?freqB = freq;
}
