Fuel Tank Strap Rust

Hello,

I have a 2012 SR5 I bought used, with a little more surface rust than I would have wanted but still not terrible. (Live in the Northeast, and the vehicle was serviced at the same Toyota dealership its whole life)

While doing a Corrosion Free touchup the other day, I noticed some rust under the gas tank skid plate. Doing some research, I noticed these are the fuel tank straps.

Both the front and back have signs of rust, as shown in the images.

Was hoping someone here has had a similar experience, and could shed some light on when I should consider replacing etc. I have seen some other threads for 3rd and 4th gens, so I am hoping maybe mine are't completely rotted out

Cheers and thanks

Apologies for the double post, but got better pictures of the rear strap for reference:
