For example, about layering, I think that layering is sometimes one of the
properties that allows complexity with robustness instead of fragility,
and that very careful, explicit, and conscious communication between
layers, when necessary, might be one of the strategies that allows
layering to work.
The hourglass: layers above and below permit complexity while retaining
core simplicity. May I add a comment to your document: a robustness aspect
[you could point out as "communication between wg-layers"] is end to end
lexical and grammatical consistency in their specifications. jfc
