Most of you seemingly go directly to the "remove the target lock once a unit left intel range" option, but as Jip already alluded to, there are other possible changes too.
For example, you could make it such that a locked unit always shows it's accompanied radar signature. That'd remove the unintuitive part, where only some units magically know where their target is, while keeping the balance of being able to kill bombers/drops reliably, intact.
Tbf, this change would bring other (balance) problems with it, so implementing it exactly like I just suggested it is not a good idea.
The discussion of "intel consistency" in the game is an interesting one though, with at least some possibility for making the game better
