We will discuss the possibility of implementing such, but I do not suspect it will be a priority item at this time (but we may do it anyway for that subset of problems we decide is sufficiently simple). If you want to implement something to do this, try solving the equation first, and converting the rules that result into equations. If the result contains no parameters or is linear in the solve variable, then simple substitution of values will show whether to convert the equations to greater-than or less-than inequalities.
