I think all DCC systems work that way --- given the difference in frequency this is inevitable. Although my Compact takes an AC input, it will be rectifying and filtering that to produce DC from which it creates the DCC signal. Several systems document that they will accept either DC or AC input.

Non isolating points are undoubtedly convenient. Effectively the same as the practice of adding local wiring around each point (which also works with electro frog points).

Can one ever create dead track for programming decoders and how do you know that the track is live?

A simple switch perhaps. You could probably use a resistor to limit the current on a 'programming' track.
