The Gentiles get mercy because there is mercy in the Gospel. The same for Jews. Rom 11 is not about the 'blocking' of one group or another, because God works with all individuals (a Jew wrote it)--unless they want to be. The NT writers may generalize but it's not even true of ALL Gentiles, is it. Just that there was an influx.
The question remains whether Jews will realize that nothing at all is based on race. It must be based on faith. That is the true 'tree' of the tree imagery of ch 11.
'God does not owe anything to anyone.' Rom 11's doxology
Hi and it is BASED on race , the JEWISH RACE as Rom 11:26 says , and so all ISRAEL will be Saved and clear to us !!
