I'd been working for years in a workplace that tests virtually everything up front until I joined a startup, and I agree with you.
Experimental features may be very short-lived, or require extensive tweaks, and the technical debt that accumulates from not testing may never arise over their lifetime. Once you're sure it's going to stick around forever, do it right and cover it with tests.
