i think it makes a lot of sense. turning on these kinds of checks can be scary. the current situation is mostly no-one is effected by bit-rot. this is probably because when it rarely happens it flips some bits that don't really matter anyway. but as soon as you turn on checksumming in software without any automatic error correction people are going to start freaking out when their files become inaccessible or they have to jump through some hoops to access the 'corrupted' file which looks entirely fine to them anyway.

same deal with some heap protections. say you are running a kernel which doesn't have byte patterns to detect heap overflows or reuse after free. maybe you have some heap overflows which because of their nature never cause any corruption but now you turn on heap protections and peoples kernels are getting more panics :/
