Yes. In the sense that current gen figters are often called upon to strafe ground targets, in the absence of air targets. Even in less asymmetrical warfare, its very common for there to be not very many ground targets for periods of time, and then a whole bunch all at once. This means that while we can have dedicated ground attack planes to take up the baseline loads, it's useful to have fighters able to take up the slack on any variable load spikes, even if they aren't quite as good at it, they can be used for other things when demand isn't quite so high.
