Maybe not extra weight, but certainly mass attached to the fork legs. Any fork designed with having a rack or cages attached will (or should according to ISO) be tested with different load cases than a normal fork.
Any strap-on system won't cause too high crushing forces on carbon. P-clips or hose clamp type things may.

It's looking great so far. It might be a 'stupid' design if you wanted to sell them and make money, but as it's a hobby and just for you then why not take the time! I often have to remind myself with DIY projects that I am doing it for fun and therefore I should just slow down and enjoy the process and challenge rather than trying to get it done quickly.

For the ETRTO designation, the stated width should the 'nominal section width' i.e.'the section width from sidewall to sidewall of an inflated tyre on its theoretical rim'. It may be that the other size being stated is the 'overall width' which is basically the tread width.
In ETRTO, they only describe this for tyres where the tread is wider than the sidewall. This is what I have found WTB do for example with the Venture tyre. The ETRTO measurement is 37-622 for the casing, but the tread is 700x40. -
This bike is almost finished! I've mislaid the front axle, and I've stuck some Teravails on there for now as the Challenge tyres lived up their name...
I will probably drop the bars once I've ridden it a bit, was too nervous to do the chop in one go. I will also swap the groupset for 2x in the summer.
Super happy with how it's looking, let's hope it rides nice too. I know the spacers / stem looks very chunky as it is now, unfortunately with this system I'm a bit limited, but over time I'm hoping to 3D print some spacers which will allow me to run different combos.
It's a shame to hear that TBA has closed their doors now, they were a great team.

It is not suspension. It is a way to allow the rear end of the bike to flex a bit more than usual without putting huge stresses on a carbon T-joint. This might be useful if you have a really rigid seatpost (i.e. dropper) or are underbiking. Bear in mind that the front of the bike already flexes very differently to the rear. A straight fork with a stem and handlebar =/= a closed triangle with a seatpost on top.

Are the spacers on the trainer correct? Sounds like you need a bigger spacer on the drive side to move the derailleur away from the cassette.
