Modern front bumpers/fascias have very little strength in the center. I'm not advocating cutting holes in them, but I used to run low speed bumper tests on trucks at Chrysler. You're likely looking at a couple hundred pounds of load at most (that it can bear in the center).
The vast majority of the load is in the crush can/bumper attachments in front of the front frame rail. OEMs will use various methods to handle the low speed bumper tests (brackets that yield, tubes that crush, etc.). The idea being you can replace a bumper assembly and hardware and won't have any permanent deformation in the rail or companion brackets themselves.
