FreeCAD is indeed smart enough to handle pockets correctly, whos Sketches are attached to faces. However, due to other reasons this is not recommended.

Maybe it is now - I'm running the repository head version and will test. I definitelty saw it being stupid this way in 0.18.4, I had to ask about it and was told about the "Reverse" checkbox, which indeed fixed the problem.

Please avoid terms such as 'stupid'. They unnecessarily charge the discussion. Everybody makes mistakes, but the word 'stupid' seldom applies.

I would like to see that example. Pockets of sketches attached to faces worked in 0.18 definitely the same sensible way as they do now: they go into the face (or rather into the material behind the face). Did you receive that recommendation here in the forum?
