Hmm that's fair. I think for most hobbyist applications though it really is gluing a bunch of things together, up until the point where you have two get FCC certified or stuff behaves erratically and you have to go and learn this stuff.

If you're dealing with low speed (ie: 50MHz bandwidth aka 20ns rise/fall times or slower) circuits, then you don't need an autorouter. Just connect every pin of your circuit together and you're done. You might need a via to cross into and route inside of your ground plane, but at low-frequencies that's not a big deal because it'd be literally too small to be an antenna and radiate off. Its just an effect that you can almost entirely ignore. If ~20MHz is the highest speed signal on your entire design (ie: ~20ns rise time, which STM32G0 or PIC or AVR beginner-friendly chips are around), then your wavelength is 15-meters, meaning the quarter-wave antenna would be (at a minimum) 3.75 meters (12 feet long), which is just far larger than any PCB-circuit a beginner will ever come across. (And will only in practice, be an issue on cables running off-board).
