What to do if the wall has too many repairs?
If i understand your question you just want to know if many patched holes compromise the structural integrity of the wall.
No the structure would not be compromised by many holes.
The wall itself may not have the integrity to hold photos or things hung on it but the wall is not going to fall over.
It is theoretically possible that if there were many holes very near each other and if someone pushed on that spot that it could give way resulting in a large hole, but the structure of the wall would still not be compromised.

Underneath the compound the support is gone (concrete, wood, etc.)

Drilling many holes anywhere in drywall does not mean the &quot;supports&quot;  holding it are gone, or compromised.
If your question is about trying to hang things where there are many holes then you need to EDIT your question to be clear on that point.
