Maintenance in general is a burden much greater than CVEs. Exploits are bad, certainly, but a bug not being exploitable is still a bug that needs to be fixed.
With maintenance being a "large" integer multiple of initial development, anything that brings that factor down is probably worth it, even if it comes at an incremental cost in getting your thing out the door.

Do you? Not every bug needs to be fixed. I've never see a data race bug in documented behaviour make it past initial development.
I have seen data races in undocumented behaviour in production, but as it isn't documented, your program doesn't have to do that! It doesn't matter if it fails. It wasn't a concern of your program in the first place.
That is still a problem if an attacker uses undocumented behaviour to find an exploit, but when it is benign... Oh well. Who cares?
