Unfortunately, for a whole series of reasons that've been evolving for probably over 100 or more years in golf the perception of what bunkers are supposed to be and to do in golf has almost totally changed. In effect almost an about-face has evolved in the perception amongst golfers of what they are supposed to be and do.
The complication arises in that for most people even beautifully and consistently maintained sand bunker surfaces are still tricky to play out of but with elite players it's basically a total snap as they are the only ones who seem to have acquired the skill to recover consistently from them. In this way bunkers are now not much more than another totally maintained part of the course where elite players consistently apply a separate skill set.
This is pretty ironic when one considers what bunkers in golf were originally intended to be and to do which was basically arrange, set and dictate golf strategy for all. They do that effectively only when their sand surfaces were unmaintained. Obviously elite players probably objected to this first since they're the first to resist one of their skill sets being reduced to almost total randomness and luck.
One might even try to draw some analogy to unmaintained sand surfaces with the randomness and luck of recovery from rough, even for elite players. Perhaps that analogy has never and would never work particularly well as there's nothing particularly defined in golf with rough as there is with bunkering so what you're actually "getting out of" is not so analogous.
Not to mention the fact that "rough" has no definition, distinction or segregation within the Rules of Golf from the rest of "through the green" areas.
I feel that one of these days some high profile club will decide to no longer maintain (rake) the sand in their bunkers and will make it more than evident why they've decided to do that by using a prominently displayed sign for all to see (perrhaps on their scorecard too) that says:
"Our bunker sand surfaces are unmaintained (unraked) on purpose, and if you have a complaint about that our only advice is to simply do your best to avoid them."
