The first time Laser-Frequency Combs (LFC) have been considered for the use in astrophysical experiments was back in 2007 in the context of CODEX@OWL. Their main purpose has immediately been identified to serve precise and accurate wavelength calibration of high-fidelity spectrographs such as HARPS and later ESPRESSO. In the meantime, almost every EPRV spectrograph around the world integrates such an LFC with more or less success. Nevertheless, none of them meet all the performance requirements and the reliability originally specified. In my talk I will try to summarise the requirements towards an LFC necessary to high-fidelity spectrographs, and give an overview of present achievements and limitations. I will also try to illustrate why such LFCs will be of valuable use beyond 2030, once the original requirements will have been met.
