The bulkiness/ugliness of the adapter is not the biggest problem. The Sony PDAF adapter is a bit of outlier. It's expensive, and I doubt very many photographers are using it. The bigger issue is using lenses designed for larger SLR cameras on smaller mirrorless bodies. Let's face it: the main point in favor of mirrorless is the smaller size. Match a small mirrorless camera with small, native lenses, and you have an excellent camera system for travel. Match the small mirrorless camera with large SLR lens, and you merely have a fraken-system: large, cumbersome, difficult to handle, and conducive only to frustration and grief.
Case in point. I know of a local photographer who shoots the Olympus 12-60 lens with an OM-D EM-5. He's an old school photographer, and shoots on a tripod. Now that 12-60 lens, with a WR adapter thrown on it, weighs around 650 grams. It's much too big for the little EM-5. On a tripod, the torque weight ended up causing damage to the bottom of the EM-5 (which, like many mirrorless cameras, is mostly made out of plastic in order to keep them lighter).
In general, what we see with Olympus' transition from four-thirds DSLRs to m43 illustrates why adapters are not a viable solution for a move from SLRs to compact mirrorless. Even though the adapters are electric, many of the SLR lenses auto-focus poorly on most m43 cameras. And even where they focus better (like on the EM-1), the SLR lenses never quite manage to focus as well on the m43 bodies as do native m43 lenses. Ergonomically, the bigger SLR lenses are cumbersome on the smaller m43 bodies, defeating the whole purpose of going to mirrorless in the first place. Consequently, prices on the old SLR glass have plummeted. I've seen used copies of the Olympus 14-54, an HG lens, selling for as low as $120 (a fifth of its MRSP). Olympus' transition to compact mirrorless has cost the company millions.

It won't be changing any time soon. Photographers, both professionals and "enthusiasts," have invested far too much money (quite literally millions of dollars) in big, expensive SLR lenses. Those lenses aren't going to disappear overnight. The photographers who own those lenses are going to demand cameras suitable for using them.
Compact mirrorless is going to be part of the future, but it will not be
the future. That's merely a gearhead fantasy. Right now, there's a too many companies pursuing the compact mirrorless market, and as a consequence, none of them are making any money. Why should Pentax enter an over-crowded market that isn't generating profits for anyone? Doesn't make a lick of sense.
