This is similar to a situation we often deal in electronics repair business. Some people are very adamant about being careful when reworking around water damaged components because those solder joints/balls/legs are already weakened, when in fact the proper procedure is to rip out and replace everything compromised. Whats the point of turning device back to working electrical order while leaving it mechanically deteriorated - it will come back broken the first time used bumps into something, or when the eaten away solder ball finally gives up after few more heat cycles.
Any time someone would say "be careful or it falls apart" its time to remove/replace it, not pass along hoping to make it someone elses problem.
