But we are in Australia.   Different rules apply!  If there is a way to make things more difficult, we would run with that.

QR has gaps in the overhead across some roads to allow for high loads on roads in the coal network. Considering 100,000's tonnes per day of coal run across these gaps, I'd say its a no brainer.

The gaps in the overhead are not an issue as the coal trains have distributed power.
So there are always locomotives under power.

true, and suburban trains in 3 car sets with just one pano still have insulated gaps although alot smaller at around 0.5 - 1m between sections

If its about allowing some LX's to have high clearances, then its still probably ok if required to approach at speed and/or installed with capacity battery backup. Battery technology is now approaching the point where costly and/or complex OH sections can be avoided especially where that piece of track is lightly used by electric trains.
