As I said, it makes no difference because the normal way to call it is 
by using calling Vtiger_Record_Model::getInstanceById() first.

It is _this_ function which finds your "MyCustomModule_Record_Model" 
class and instantiates it. (But this is the child, not the parent).

Also in certain places in vtiger, where you might want to access an 
existing Record Model, say in the DetailView module, you call 
$this->getRecord(). This Record Model was instantiated by the 
Vtiger_Record_Model::getInstanceById() call so again you can't really 
extend the function because it has already been called. The only way is 
to explicitly call your own custom method in your Record Model is to use 
MyCustomModule_Record_Model::getInstanceById(). Which is what I am doing 
for now.

being able to pass a callback/method parameter to this at the vtiger 
level might work for most situations, but not all as described above.
