Electronic Data Interchange in the era of Internet?

I am writing a small essay on EDI. Based on my research so far(claude, google etc):

- before internet era edi relied on VANs(Value Added Networks) making it more inexpensive and unapproachable to small businesses.

- After internet era, EDI now relies on FTP,AS etc protocols. Thus it is affordable to even small businesses

Obviously in the era of internet, EDI infrastructure is not needed anymore(cause it is expensive). However I believe the EDI message format might still be useful.

Am I correct? What else would you add to this?
