PGMs are very expensive , used selectively.
Aircrafts using CCIP and importantly CCRP modes can deliver dumb gravity bombs with high levels of accuracy and for mass attack by multiple bombs ( carpet bombing ).
Only disadvantage is the low range and to some extent the high altitude required for bomb release ( depends on the bomb types )
Eg
In LCA in CCIP ( constantly calculated impact point) mode the fire control computer displays on the HUD where the dumb bomb would hit if dropped at that moment. As the terrain and flight path changes, the dot moves. One simply maneuvers the plane to put the dot on the target, and when on the target the weapon is released/fired.
And LCA when utilising CCRP (Continuously calculated release point) mode uses the radar to pick a target. The radar then locks onto that target. On the HUD, there will steering cues for the pilot to follow, computed by the the fire control computer.
It's basically a vertical line, with a small horizontal line called the bomb release cue that slowly falls towards the center of the HUD as the pilot approach the target. the pilot will get the distance and time to target displayed on the HUD, counting down.the pilot will hold the release button and the computer will automatically release the bomb when it meets the previously calculated parameters .
CCRP mode is used with both dumb and precision weapons. even without target lock/designation one can release bombs in CCRP mode by simply feeding the coordinates of targets, the fire control computer will do the rest.

Why do you think IAF was praising LCA weapon delivery capabilities ?
Any aircraft including crop dusters can drop a PGM with accuracy with the help of a EO pod / LDP , But only very few aircrafts can drop dumb bombs with accuracy even without the help of any external sensors.
