I think there's probably two ways to address this.

1) Most likely we make self retracting reels, or just very easy cable/slack management and sell fixed length cables with a hard connector one end and a snap on connector the other end (https://youtu.be/6dop-9_0_g8?t=43&si=DdAXLMU_A7wTuCTn). That solves the problem of accounting for the plug in drilling holes. We could easily do this tomorrow on 2mm white 1f or 3mm 2f cable. This size is important as it is about the maximum you can just use adhesive to stick to the top of skirting.

2) we use plastic optical fibre and build a whole bunch of infrastructure around that. That is much easier to terminate, cut and safer to use but a load of work will be required.
