Put this way, I can understand your desire to distinguish between guidelines and rules. I don’t really see rules that tell you you can ignore them if you feel like it as carrying much weight to begin with, and my way of trying to understand what is supported by the text is to give weight to the guidelines as well as the rules, so as to arrive at the way the system as a whole is intended to be used (which I seem to have done pretty well, given that developer comments agree with my ruling). But still, I can understand the desire for such a distinction.I would agree with you that most of the DMG consists of guidelines.
Guidelines are a flexible way to advise DMs how they might run the game. With guidelines, it's okay to have contradictory statements because they don't have the weight of rules: readers don't need to decide or agree on which prevails. What prevails is whatever the reader wants to take away from the guidelines. My stance is that in conjunction with other designer statements and community norms, guidelines give us RAI.
Thar said, I take issue with calling a rules-only reading “RAW” and rules-and-guidelines reading “RAI.” If you are comfortable expanding the R in RAI to include both rules and guidelines, there is no reason not to expand the R in RAW the same way. And given that the guidelines in question are written in the text, and are as often in need of clarification on the intent behind them as the rules are, I believe RAW is the more accurate way to categorize them.
