RAW as a trend
This is not a trend and has been around for as long as game rules have existed. In its purist form, it is a defense against an opponent trying to expand on the interpretation of a rule. Some players' ideas of how a rule should be naturally extended to cover situations in game play can be quite expansive. In its most restrictive form it can be used to disallow seemingly logical gameplay based on semantics. I know of one instance where a player tried to claim that another was not playing by the rules because the rules were written to "add up the pips" on dice and the one player was using dice with numbers instead of pips. In either extreme, for tournament play, one requires an impartial referee, and in friendly play one might require new friends.
