I am a little uncomfortable with some dnd-5e questions. I would guess what I am going to address in this question might be an issue with any other RPG which is still in the process of being updated/improved, but I will restrict myself only to dnd-5e; as it is the most obvious example on the site at the moment.
Please have a look at the following Q&A: Can a weapon be both adamantine and silvered?
The question is reasonable, but the answer is bothering me. The core point of the answer is that there is no current rule which is inhibiting the silvering process to be applied to adamantine weapons. But there is a difference between saying "no rules forbid this" and "yes it can be done".
Now I feel part of the reason why we, the answerers, equate the above two statements is the stance of D&D 5e designers themselves. They try to maintain that the rules are all encompassing, in the sense that if something is not expressly forbidden, it should be doable. However, this is such a bold statement to make: a couple of gaming books cannot cover the laws of an entire fantasy multiverse, the answers to some questions are better left to the gamers themselves. (See this question as a 'trivial' example of why we don't expect that the rules are meant to cover everything about the gaming world, such as basic real-world optics.) One must accept that some things are bound to have been missed by the game designers.
Note that it appears that they themselves occasionally reinterpret the rules as they see fit, but strangely there appears to be a culture of encouraging everyone else to follow RAW strictly. (When I say everyone else, it is really the community here at rpg.se, as I do not follow any other forums.)
Let me illustrate my point with two concrete examples:
https://twitter.com/JeremyECrawford/status/629526633683103745 See how Mike Mearls himself implies that the auras of multiple paladins do not stack, but how he is "diplomatically" corrected by Jeremy Crawford. It seems obvious to me that the two of them think (or thought) differently on the topic.
https://www.youtube.com/watch?v=EWOsPhKNyPk#t=27m20s See how Jeremy Crawford is "retracting" the possibility of true polymorphing creatures to magic items.
I don't know if anyone else is bothered by this. I feel that if the answers were given in the style of "nothing RAW bars you from doing that", the site would become "more neutral". I just want to know what people (particularly the older residents of the site who might have experienced these sort of things in other games) think. If enough others think similarly, is there anything that can be done to encourage the more neutral style?
