Yes, and that is why the F-35 can't replace the A-10, it is too fast, it can't loiter in the combat area & pick targets when they appear, this makes the F-35 a bad ground support aircraft when battles prolong for several hours.
Except "loitering and picking targets" isn't how Close Air Support is being done these days anyway. It introduces too much risk, because there is always the "fog of war" and confusion on the battlefield. If your pilots are picking targets with the Mk1 Eyeball, there is a decent chance they will pick friendly forces, or civilians, by accident.
That's why we are moving to digitally-aided CAS and precision munitions. Of course, if we get in fight with the Chinese or Russians GPS will be jammed to Hell, so that needs to be taken into account too...
