The weirdest part is how many people think depositors should actually take a haircut, or that is should be on the depositor to prove the financials of their chosen bank for bankruptcy risk. Not really a view of Silicon Valley though, unless people making said comments are from Silicon Valley.
How bank runs were historically handled in the US is that the depositors lost all of their money. Banks runs are a recurring problem that have a history going back hundreds of years. That's changing now though, the SVB depositors will be made whole by the government in order to avoid a wider banking crisis and what that means for everyone else is TBD but it looks like some form of insurance that's better than $250k.
Post FDIC, bank runs were historically handled by the FDIC either merging the bank with a solvent one, or taking it over. Depositors below a certain amount lost exactly $0, amounts above that were at risk. That amount was currently at $250,000.
What's new is that depositors above the threshold have been made whole.
