I agree it's great, but that risk is so major that I stopped using it. "There's a 50% chance that your editor will invisibly corrupt the data you enter, and another 30% chance to corrupt the entire file" is just not usable...

Especially in Zed where the only way to switch hard tabs is buried in the settings menu, and impossible to change per buffer.

You'd think more editors would be smart enough to recognize that it's a TSV file and therefore should preserve the tabs, in much the same way that you'd think editors would be smart enough to recognize that something's a Makefile and therefore should preserve the tabs.
