Accessibility compliant PDFs are not just important but often mandatory. Many large corporates, governments suppliers are required by law to supply information published online in an accessible format. HTML5 is an obvious choice; often workflows require accessible PDFs.

Even if you don't need tagged PDFs for accessibility reasons, there are many benefits to understanding the text flow embedded within your PDFs.
