There's a good thread debunking this myth
here.
Your networks might be dying-- and well, I guess that's a good thing, since your networks don't seem to support sane encodings anyway. IRC as a whole is not dying, though.
Sorry, the actual question was:
You said "it will be implemented", but I wasn't able to find where Khaled said exactly such. Also, I'd like to know when it will be implemented, at last approximately. Some of further betas or may be even 7.1 or 7.5 or whatever?
I find this more important.
