This is wrong, a redstone signal can pass through solid blocks since the block can be empowered.
Any device placed on such block will be powered and if you need to extend the signal from said block you just need to place a repeater facing outward.
A device powered this way will not propagate the signal to adjacent blocks and this is also the only way to avoid powering multiple devices when they're close together (i.e.: 2+ droppers).
Using solid blocks whenever possible is also a good way to use less redstone and make the circuit more survival friendly.
