It could be a death-by-a-thousand-cuts situation and we don't have enough context. My company has spent the last few years really going 1000% on the capitalization of software expenses, and now we have to include a whole slew of unrelated attributes in every last Jira ticket. Then the "engineering team" (there is only one of these, somehow, in a 5K employee company) decrees all sorts of requirements about how we test our software and document it, again using custom Jira attributes to enforce. Developers get a little pissy about being messed with by MBAs and non-engineer "engineers" trying to tell them how to do their job. (as an aside, for anybody who is on the giving end of such requirements, I have to tell you that people working the tickets will happily lie on all of that stuff just to get past it as quickly as possible, so I hope you're not relying on it for accuracy)

But putting the ticket number in the commit ... that's basically automatic, I don't know why it should be that big a concern. The branch itself gets created with the ticket number and everything follows from that, there's no extra effort.
