Aren't there inherent advantages to correct and semantic code, advantages like performance, simplicity, understandability, expressivity, that could/should benefit the business?
Lots of team leads don't focus on these solutions and their benefits but rather on the most recent technologies and their own benefits while ignoring (or accepting as inevitable) their costs. The longer you look in that direction, the harder it gets to see what you are missing or could get by looking elsewhere.
Accessibility is one area I've seen an overlap. It is still rare, but I have been on a couple teams where accessibility was a metric and it largely lead to better DOM structure and semantic HTML.
