While I'm not arguing the value of falling back to LIRC's default config 
file in the event there's no ~/.mythtv/lircrc (I'll leave that decision 
up to someone else), I think the current implementation will work for 
what you want.

Other clients that will only use ~/.lircrc /force/ you to commingle 
settings for many different programs in a single file (although, I'm 
sure many of those you're including in this group allow you to specify a 
config file with a command-line option).  MythTV /allows/ you to choose 
to keep your MythTV settings in a different location /or/ to use the 
same config file.

 From man 1 lircrcd:

-o, --output=socket
    With the --output option you can select the Unix domain socket, 
which lircrcd will create. The default is to append a "d" character to 
the config filename given.

So, to synchronize mode against all clients, where most use ~/.lircrc 
(and the default socket for lircrcd), wouldn't you just make sure the 
line in your MythTV LIRC config file (~/.mythtv/lircrc) is:

#! lircrcd -o ~/.lircrcd

(I haven't tried this, since I'm using an older version of LIRC, but it 
sure seems that's what the designers of lircrcd envisioned.)

If you want to have all your LIRC settings together in one file (which 
is my assumption here), you can simply take all the settings out of 
~/.mythtv/lircrc and append them to the bottom of ~/.lircrc with 
something like:

cat ~/.mythtv/lircrc >> ~/.lircrc

Then, create a symlink from ~/.mythtv/lircrc to ~/.lircrc:

ln -sf ~/.lircrc ~/.mythtv/lircrc

Now, all your settings are in the same place and there's only one LIRC 
config file to deal with.  This won't help with the socket issue, but 
that's what --output=socket is for...
