Transparently passing on options to other functions

Let functions f and g be defined as follows:

f[ OptionsPattern[{}] ] := OptionValue[optf];


Options[g] = {optg -> True};
g[opts : OptionsPattern[]] := OptionValue[optg] && f[opts]

The following gives a warning that optf is not an option value for
function g.

g[optg -> False, optf -> False]


Is there a good way to have OptionValue ignore this fact and not generate
a warning? What is the proper way to transparently pass through options to
other functions?

I would like to not do the following:

Options[g] = {optg -> True, optf -> Null};

which eliminates the warning.
