Go for it.  My only reason for using eqn(1) is tht 99% of my needs are 
because of mathematics. You examples of footnotes to text and chemistry 
formulae are clear examples where they are not needed. That said, I never 
use superscripts for footnotes and use the 'roman' keyword in eqn(1) for
chemical formulae.
