Yes! By all means.

I'll strongly recommend that the MFG members take a look at the
following books, unless of course they'd rather create a
"TeX for poets".

"Gravitation" by Misner, Thorne and Wheeler

"Elements of Green's Functions and Propagation" by Barton

"Foundations of Electromagnetic Theory" by Reitz, Milford & Christy

"Solid State Physics" by Ashcroft & Mermin.

All of these books, especially "Gravitation" use a variety of
uc and lc greeks in bold, bold italic, sans , sans bold, sans bold
italic etc. Instead of the obvious way of typing a formula like
${\bf\tau}={\bf r}\times{\bf F}$, God knows how a user will be able to
typeset such a formula, assuming that the Cork encoding together with
the new proposed math encodings are adopted. By the way such a formula
is in each and every introductory physics textbook. There are
many many other examples I could give from physics where one
would need greek letters from a variety of different typefaces.
${\bf\mu}$ for magnetic moment, ${\bf\sigma}$ for Pauli spin
matrices, ${\bf\beta}={\bf v}/c$ etc.

I am curious as to how many members of the MFG have a background
in math, physics or engineering. After all TeX was primarily
intended for use by people in these professions. It's one
thing to be able to get a ${\bf\beta}$ that is perhaps
positioned slightly less than ideal and perhaps wait 10 extra
microseconds for that. It is quite a different
matter *not* to be able to get it at all.
For a practicing scientist in real life, the choice is quite obvious.
I wish members of MFG could see that most people who use TeX are
not "TeX-hackers". They simply want to write a paper or a book
without having to deal with all sorts of idiosyncracies. In
short they need a *tool* not a hobby. I have to say that I have
seen many people who are turned off by TeX solely
because of its "awkward" behavior (\bf\Gamma vs. \bf\gamma for example),
not because a superscript
was 13 microns higher than it might have been.

A little common sense never hurts. Or shouldn't.
