Is it necessary to have a separate power district for every signaled block? Thanks.

No.
For what I use (MSS ABS signaling), the number of power districts does not matter.

If you are using current sensing to detect a train you simply need to cut gaps for the signal block and run the DCC feeders within that signal block through the current detection circuit. The signal block can be all or part(s) of a power district.
If you use optical detectors then no additional gaps are required but you may not have the ability to see a short train moving or standing within a signal block.

With normal current detection, you will need resistor wheelsets on many/most of your cars. Otherwise, once the loco leaves the block, the rest of its train becomes "invisible".
With MSS, current and optical sensing are combined into a nearly ideal detection system, and without the need for resistor wheelsets. Or a computer, for that matter.
