IMO the code-generation for boilerplate and the improvement of copypasta quality are much bigger improvements than that.

PMs turning their brain off and letting the LLMs extrapolate from quick and dirty bashing of text into a template (or, PMs throwing customer feedback at a slackbot to generate a jira ticket form it) can be better than PMs doing nothing but passing ill-defined reqs directly into the ticket, but that's a low bar. And it doesn't by itself solve the problems of the details that got generated for this ticket subtly conflicting with the details that got generated for (and implemented) in a different ticket 8 months ago.
