Not really - what they’ll do is put in the date tag some much more recent date than the date of publication to try and push the content towards search engines to make it more likely to show up, lie about stock levels (say some product is in stock in the metadata, but say on the page it isn’t in stock), cram keywords into metadata, stuff like that. I don’t think it’s really an improvement.
Unfortunately, people play a lot of weird tricks with semantic tagging for SEO, making them less useful to screen reader users. Not to mention that Google has a very specific, very limited interpretation of the tags, so a lot of tags that would be useful for accessibility are unused or misused.
