Stuck pistons stay stuck forever

Steps to reproduce :
-Power a piston while it is stuck, then remove the block that blocked it
OR
-Build this flying machine

What I expected to happen :
-Since nothing blocks the piston and it is powered, it should extend

What would happen in PC edition (probably unintended)
-The piston would stay stuck until receiving a block update

What happened :
-There's no way to extend the piston without removing the redstone block

Maybe this is intended, but it is :
-Very bug-like
-Not QC
-Super annoying for flying machines (worse than the removal of QC)

A theoretical way to update unstuck pistons without slow useless updates :
-When a piston is stuck, go to the block or blocks that blocked it (up to 12 blocks) and those blocks "remember" they blocked the piston
-When a block changes, it looks at the list of pistons it blocked and updates them.
