This is what I learnt years ago, & as such devices are still not commonly used at RF, would still seem to be correct.
Gyrators, by and large, are not useful in RF circuitry, as at higher frequencies, stray capacitance & inductance become large enough to affect the circuit performance.
Real LC circuitry can be designed which minimises such effects, or even incorporates them.
Possibly, if Gyrators are built as an integral part of specialised ICs, it may be possible to overcome these pproblems.
