Drain holes OR rot in front floor........

Working in the front floor area of the car I have found two holes that appear to be manufacturer holes - in the the recessed dimple that run under the front seat centre and to the angled section where the drivers/passenger feet rest.

They are about 7-8mm diameter and don't appear to due to rot - unlike some of the other holes I have found in the floor

Should these holes be there?????  They were covered by the original sound mats/bitumen that I have removed.

Are they drain holes??????

Hope the photos make sense………

Yes the big round holes are meant to be there.

Just to explain I am asking about the small hole in the photos - NOT the large holes in the footrest panel.
