I don't buy that. The main issues with merging are, as far as I can tell:
- conflicts in the syntaxes of telnet and remote control,
- lack of separation between the input/output and the interpreter,
- lack of design in general.

Instead of implementing two commands interpreters (LUA VLM and LUA RC) and two 
input/output (socket and console), the two interfaces were written as two 
incomplete rewrite of the C ones. Thus, instead of addressing the bugs and 
code duplication, it made things just worse.

And then, I do believe that separating I/O and parsing is easier in C than in 
LUA. First, the module bank is not accessible from LUA. Second, I/O 
multiplexing and event handling is far easier in C, than in LUA.


To add pain to injury, the LUA interfaces were promoted, and the native 
interfaces marked deprecated, way before they were feature-equivalent. And 
then, the author ran away. Oh sure, old RC was poorly written. But it does not 
look like LUA RC is that well written either.
