Good question (although the IRS still does not even have the capability of processing certain returns electronically, such as Form 1041 returns for estates to which section 1398 applies).
There might still be some clients who insist on paper filing (I can't think of any in my practice, though).
Regarding returns sent to the IRS centralized insolvency unit in Philadelphia with Bankruptcy Code section 505(b) prompt determination requests, the taxpayer is actually at an advantage by being required by the IRS to send a paper return. Philadelphia cannot process these electronically. However, the IRS argues that the "Philadephia" copy isn't really the "filed" copy anyway -- that the official, "filed" copy is the one that goes to the Service Center or "Campus" (e.g., Odgen, for 1120, 1120S or 1065 returns from Texas, where I am located). Especially in this COVID-19 era, Philadelphia probably isn't able to process the 505(b) requests and respond within the statutory 60-day period -- so that's a big advantage for the taxpayer in terms of obtaining the 505(b) discharge.
EDIT: Another reason for filing by paper is the limitation of the software. The Intuit Proseries software that we use cannot handle returns with amounts over a billion dollars -- either by paper or electronically. We have only a few clients with total assets or net operating losses of over a billion dollars, and a decision has been made that it's not worth the cost for us to upgrade just to be able to have software that will handle those returns.
