Even if it's mentioned in "The LaTeX Companion" I don't see any good
reason to bother a casual user with such low-level stuff.

I fear that redefining \tiny has no impact on math formulas.

Why do you assume that they don't know anything about typography?
They noticed that fonts smaller than 7pt are incomprehensible.  This
is a reasonable decision.  At least unless the fonts used are
especially designed for this particular size.  And only Knuth's fonts
support "design sizes".
