It hasn't been helpful enough to be justify the maintenance burden. What actually does help is mprotect(), kprintf(), --ftrace and --strace which can always be counted upon to work correctly. We aren't losing much with this change. Support for ASAN on AARCH64 was never implemented. Applying ASAN to the core libc runtimes was disabled many months ago. If there is some way to have an ASAN runtime for user programs that is less invasive we can potentially consider reintroducing support. But now is premature.
