Imho math fonts should be fix fonts, they should not like \textbf
switch one aspect of the "current" font but always to a fix, well
defined font.

Also chars should not only look ok but in the days of unicode also
have the code point with the correct meaning. That means that a bold
"T" in math should if possible be the one from the math plane in
unicode and not a bold "T" from some textfont -- even if they look
the same.

So in my opinion the current \mathbf-etc setup in unicode-math
actually did the right thing and improved the standard
\math-commands. I wouldn't like to loose this completly. If \mathbf
pointed to a textfont then everyone who wants the real math symbols
would have to replace \mathbf in their code by \symbf. And back
again if he wants to use a text font.

Wouldn't it be possible to have a "\usetextfontasmathbf..." command
which disables the mapping to the math plane? So that one doesn't
have to switch between \symbf and \mathbf depending on the font
setup of a document?
