Yup! I used to feel exactly as you do, and I make it my business to understand what is below the abstraction besides because some old habits die hard (and because I just like this stuff, tbh). But I started working at places with the kind of conservation and pre-testing that make that much less critical. Those organizations also that pay a great deal of money for the kind of support to make knowledge a habit of curiosity and personal fulfillment rather than save-the-worlding.
I haven't needed to do something like that in production, as opposed to pre-production deployment suss-out, since (and I went and checked my enough to be sure) 2017. Though, to be fair, I've been working in devrel since last August, so call it four years of rooting around in the trenches, not five. ;)
