I don't think anyone here is in the position to be able to tell what is  
90% or 5%. Personally I use LIRC exclusively for transmit to my settop box  
using an old and obscure RECS80 protocol.
No, I won't replace my setup just because it's old and obscure.

Cable companies tend to provide XMP based boxes to subscribers more often  
these days. Simply not supporting these setups is a no-go for me.
