I read it as "we can't do it now because complex reasons, but we know it's still a problem and want to do it" and that feels pretty good. Like who's supposed to set the timeline for rectifying long-lived errors in judgement? Unwinding long-lived errors generally takes time.
As someone who once implemented a name change for a much, much smaller company, I can tell you this is just not so. You have to find and fix every contract, bank account, government registration, checkbook, domain name, knowledge base article…it’s endless. And some of those changes cost money in addition to time.
