You can assure that you're still alive by checking the obituary pages every day.  I've never found the IRS count to be accurate, but I have better things to do every day than check that page.  (I do check every day, though, for the skyrocketing Covid infection rate in my state.)  By the time you detect a problem, it's too late.  If the count is 100 higher than it should be, you might be able to find someone at IRS to do something in a month or two.  But if it's higher by only 5, what would you expect?  "OK, we'll pull all of your returns and find ones that look flaky."  Not sure if the cure is worse than the disease.
