Piston Transparency !!

I'm not sure how to feel about this one. Since pistons act opaque in some aspects, you can place redstone components like levers, buttons, and dust on top of them, something that wouldn't be possible if they were fully transparent. If they were fully opaque, you could point a repeater into a piston and power both that piston and the ones above and below, since the middle piston would be strongly powered and would weakly power the others. At the same time, though, pistons being transparent has the advantages of them NOT transferring power to adjacent blocks and not cutting off redstone dust.

There seems to be advantages to both, and I suddenly wish we could have both somehow, like dispensers & droppers or pressure plates. Transparent pistons that act like the Java ones (plus maybe the ability to place levers, dust, and etc. on them, and without the quasi-connectivity bug of course), and opaque ones that can power adjacent pistons, allowing for piston walls that are potentially much easier. What does everyone else think?

Please respond and add the current version if you can reproduce this issue.

Confirmed for 0.15.4. (Tested on Windows 10.)

Confirmed for 0.15.6. (Tested on Windows 10.) This may be related to MCPE-14199 or quite possibly even be the SAME issue.

Confirmed for 0.15.7. (Tested on Windows 10.)

Confirmed for 0.15.90.2. (Tested on Pocket Edition.)

Affects 0.16.0 beta build 4 AKA 0.15.90.7.

Affects 0.15.10. (Tested on Windows 10.)

Affects 0.15.90.8 (0.16.0 beta build 5).

If this is WAI, then should pistons act like solid blocks in all cases? For example, if you place a lever on a piston and activate the lever, should adjacent redstone components (redstone lamps, dust, other pistons, etc.) be powered?
