SAR Deadline Changes and Text Messages for Electronic Disclosure?

Hello, I realize that the 5500 has the special extension authorized by the IRS. The EBSA came out with its special extensions which don't apply to the Form 5500 report. However,  I wondered if the Summary Annual Report of the 5500, the SAR, as a disclosure notice, would have EBSA's Disaster Relief Notice - 2020-01 extension of March 1 - 60 days after the Covid 19 National Emergency has ended. The Office of Regulations and Interpretations has not returned my calls yet on my question. Does anyone else know? 

Also the the EBSA press release said to use a good faith effort to issue disclosures and one of the methods was text messages. When was text messages allowed for electronic disclosures? 

EBSA Disaster Relief Notice 2020-01 extends the time for plan officials to furnish benefit statements, annual funding notices, and other notices and disclosures required by ERISA so long as they make a good faith effort to furnish the documents as soon as administratively practicable. The notice explains that good faith includes the use of electronic alternative means of communicating with plan participants and beneficiaries who the plan fiduciary reasonably believes have effective access to electronic means of communication, including email, text messages, and continuous access websites.
