Sub floor question

Hi. Redoing kitchen and had to relocate air returns which were previously in the floor. Floor guys installed new hardwood but didnít install any subfloor in the opening. The areaís pretty small, about 9x3Ē. Any issues with this? I assume they should have put sub floor but it is a small area. Should I go back and install a sub floor support in that small space and then another larger piece under it to fully support the patched hole? Thanks.

Not really an issue. It was ok when the register was in the hole, and they didn't nail the floor there, so whats the difference?

Ok whatever. You asked for an opinion, and its not an issue. 100 years ago wood floors like that got installed right over the joists, and there was no subfloor.
