No underfloor heating in the attic hallway?

Our general contractor does not install underfloor heating in the hallway of the attic as a standard. Do you think that is okay?

Our HLS planner also described it as unnecessary, since the supply lines to the respective rooms usually run through the corridor and thus sufficient heat should be generated.

The areas in the hallway on the upper floor are generally quite small, heat rises through the open staircase anyway, and in my opinion, the supply lines to some rooms in the walking area are sufficient.
I see it that way, so offers are OK.

Thank you!

Our paramedic simply laid the two supply lines to the children's rooms, which run through the hallway, generously in two loops (at 4sqm) through the hallway. So not the direct route. If you now heat the children's rooms normally, the hallway is slightly heated as well. This also seemed to us as a pragmatic solution without much fuss, additional electricity, and big ruckus. I would probably see it differently with a larger play hallway or library hallway.

We have the heating on almost only in the bathroom on the upper floor. In the hallway upstairs, there is a separate circuit, but it does not have its own [RTR], instead it is controlled together with the bathroom. This has proven to be the best solution for us.
