Interesting timing - I'm building genx.software which leans hard into implicit inheritance for the exact reason he is abandoning it. In my finance app, when the product owner changes their mind about decimal places for the 47th time (and it's always 47), the last thing I want is to hunt down every cell and add :inherited modifiers.

We treat everything as integers server-side (because floating point is the devil) and defer all formatting to the client. Implicit cascade means I can change fmt-x="currency:USD:decimals:2" in one place and watch it ripple down the entire table. It's 'maddening' the way CSS is maddening - which is to say, it becomes second nature after you stop fighting it.

That said, I fully understand the support ticket burden. Maybe the real lesson is: implicit inheritance is great when you control the domain (like 'format all money the same way'), but terrible when people want to do arbitrary things at arbitrary levels. I will bear that in mind as I complete genx.software
