As a UX designer that always gives guidance on URL design/strategy, I’ll say it’s not always well received. I’ve run into more than a few engineering or PM teams who feel that’s not w/in scope of design.
I can imagine in your situation as a pure designer how you got it though though, sorry to hear that and I wish other devs cared more. I've def mentoring people to care about it so hope others do so too.
We all are trying to understand a problem and trying to figure out the best solution.
How each role approaches this has some low level specializations but high level learnings can be shared.
