While the aircraft will never fly again, there is a great deal you can learn from close examination of weapon system components, like radar antennas.
For even a salt soaked airplane to fall into enemy hands, greatly compromises many of its performance parameters, because they would be able to do close inspection, analysis, and exploitation.
If what you said was true, about the effort, not being worth it, then the Russians would not have tried so hard, and we would not have expended the effort, when this has happened previously.
But the Russians did see value in the effort, and tried to beat us in the recovery of the aircraft.
That’s because the aircraft itself has value.
I'm not denying the intelligance value. I'm acknowledging the intelligance value, and that is why, if recoverable it needs to be destroyed to the extent that there is no longer any thing left of it that would provide information.
But I'm also pointing out that all the parts of it are scrap as far as being able to actually be used in a flying aircraft. Therefore, not worth the effort to recover, when properly destroying it is much easier, safer to do, and cost a heck of a lot less, if it is at all recoverable by unfriendlies.
Some aircraft have some titanium structural parts that might be worth recovering because they might still be totally NOT damaged, or be inteligance info to keep from unfriendlies and also survive after destroying the aircraft, but I can't see even those being actually used again. Maybe those parts would require recovering if feasible, maybe even after the rest of it was destroyed, again, only to keep info about it from unfriendlies.
It's not really my field of expertise, but I doubt the juice of a recovered aircraft that was submerged in salt water is worth the squeeze involved to recover it for the country that built it and has no intelligence to gain from it, if totally destroying it is a better option, and epically when any recovery would be in contested waters.
-----------------------
Lets just park recovery ships stationary for a day or two in waters where unfriendlies have been recently been attacking our moving ships. Yea, what could possibly go wrong with that.

An underwater demolition team from a sub that is unseen would be a much wiser and safer option, if required.
