Indeed, that’s why I talked about “dominates your thinking” (as opposed to “should dominate your thinking”).

An interesting effect of having a great FDT technique is that it becomes much easier to handle complexity.
A follow-on effect is that, as it is so much easier to put in complexity, you do put in more of that.
Which will hurt you sooner than you think (*)…

So I strongly believe that a prerequisite of using FDT successfully is that the formal model of your shiny new RFC should now fit on one slide.  (Which actually works out for RFC 7071 (+)!)

(*) I still remember when I first read the ASN.1 for GSM MAP.  All 950 pages [IIRC] of it…
