Honestly for me a BOM is more useful than the full build notes at this point for several reasons.
1) Unlike most PCB manufacturers, Robert puts the actual values right on the silkscreen, so you don't need the build documentation (with rare exceptions where there are multiple builds possible) to translate R1, R2, D1, etc. It's obvious where everything should go.
2) Having a BOM means I don't have to pull out the bag of resistors or capacitors a second time because I counted 6 rather than 7 components...
3) Drill templates (much like AionFX and a few other manufacturers) are standardized - so if you find one with the same knob layout, it should go... Heck, there is a whole CATEGORY of PedalPCB enclosures on Tayda. That being said, I end up validating and adjusting layouts as often as not (see my Whipped Cream build) to suit where I want to go with the pedal enclosure-wise.
