Yes that note assumes that the installer is pretty stupid.

We mostly use the numbers that are on the drawings. Esspecially on big jobs.
Unless it is something that is way off. .If I do move one, I'll make a note on the drawing which panel and number(s) it was moved to.

Does anybody really ever try and balance the phase legs for new installations? That old boiler plate note has been around since Tesla worked for Edison. My typical panel schedules have about 10 receptacle circuits for every lighting circuit. Balancing receptacle circuits is futile with nothing plugged in.

Generally true, but in a residential panel, for example, I will pair the two kitchen receptacle circuits, the laundry and refrigerator, microwave and bath, etc.

Well, take for instance the home I am dealing with right now from drawings. Customer has six bathrooms, on two sides of home, over two floors... in Ja that means two panel boards. If I was allowed one panelboard would set all bathrooms on one side of house on breaker five, for instance, and the other side on breaker six for instance, because they are usually different phases, with breaker five and eight usually sample phase, etc... but I had a boss that for same reason would have them both on a double breaker, just removing the tie bar... so they would be five and seven or four and six, etc...
Same with the kitchen and pantry and dining circuits.. usually I end up with everything spread in a group, and normally my kitchen circuits or small appliance circuits end up being around four per home, because local code says no more than three outlets per circuit on these circuits... unlike the USA...
plus, not allowed to use mwbc according to local inspector... can only share ground, and he prefers the ground to be as large or larger than the neutral. Most of the time he uses British rules which would allow a smaller ground..but on grounds he takes a bigger is better... however, he allows one groundto cover many circuits since we use conduit...
so often times here you can see a ground in a box that is a number ten, with number fourteen pigtails on it for the switches etc..
