Is a low value of capacitance really important? At 1GHz+, the package inductance dominates the characteristics and so the impedance of a 0.1uF and a 100pF capacitor in an 0603 package will not be very different. As you point out,
for better performance at higher frequencies one would need a lower inductance 0402.
Thanks,
