that pad runs to ground somewhere else *OR* so long as the thru-hole

Either way, it is almost certainly fine just the way it is.
10 years OK, then gradually worsening intermittent connection.
Even DURING those first 10 years, I do NOT consider that "fine".
The Board Swappers declared the board to be "NFG" and wanted to discard
it. One of my colleagues is about to get fired - of the fifteen
complaints against him for "unprofessional behavior", one of the most
serious is "took discarded stuff out of the college dumpster and
repaired it".
All reasons to repair it not to "good as new", but to "good as it was
supposed to be". Unless there was some historical rarity like "Gary
Kildall did this bad soldering", WHY would you want to keep it in a
defective state? Are you doing stamp collecting, or physics?
To bring this throughly OFF-topic, should you clean Ansel Adams'
thumbprint off of one of his negatives?
(which is more important? - the historical aspect, or the quality of it?)
