The manual, 5.5, says:

While it is nice to have these math parameters available for tweaking,
it would be tedious to have to set each of them by hand. For this
reason, LuaTEX initializes a bunch of these parameters whenever you
assign a font identifier to a math family based on either the
traditional math font dimensions in the font (for assignments to math
family 2 and 3 using tfm-based fonts like cmsy and cmex), or based
on the named values in a potential MathConstants table when the font is
loaded via Lua. If there is a MathConstants table, this takes precedence
over font dimensions, and in that case no attention is paid to which
family is being assigned to: the MathConstants tables in the last
assigned family sets all parameters.

I think it is a bit clear what we are missing now, a MathConstants
table. Just to be sure, is there any thing else we should consider?
