The \lyxmathsym macro also takes care of boldening symbols when using
\boldsymbol
(Ctrl+Alt+B), but otherwise is now a wrapper around AMS \text.

I think that \lyxmathsym is the easiest way to the uninitiated for entering
unicode symbols in math. It is also quite unintrusive as it enters the game
only at export time and almost always does the right thing. The moment it
comes in ones way, it can easily be taken away by "\renewcommand{\lyxmathsym}{}"
in user preamble. So, I think that it is useful and not dangerous.
