I imagine this could break some existing code. Especially if IANA starts to actually allocate addresses from the 0.0.0.0/8 range.
Luckily, this doesn't change the fact that 0.0.0.0/8 is still reserved by RFC8190[0]

Who's going to want to use that block? Given how many legacy devices are there on the web, it's probably not going to be reachable for a sizeable chunk of the internet.
