Repair Does replacing the sail window break rule compliance?

So, have this old training sail that I am about to sell for €150...

Before selling it, I wanted to repair the window decently because it had a bunch of holes sealed with tape / adhesive Dacron. A sailmaker advised that the only way was to replace the entire thing, so I trusted him and let him do his job.

Now I post an advert online with details on the repairs made, sail status and usage... and someone replied saying that now the sail is no longer class legal...

Now, I strongly doubt someone would buy this sail to compete seriously in bigger events, so I am not worried about the legality aspects as I doubt that the new window would give you an edge...

However out of curiosity I wanted to ask about wether replacing the window makes a sail not class legal.

Rules say:

26.1) Repairs and preventative maintenance to the sail [...] may be carried out without violation of these Rules provided such repairs are made in such a way that the essential shape, characteristics or function of the original are not affected.

26.4) Sail panels and luff sleeves shall not be replaced.

Now... I imagine yes, but does the window really count as a panel? I thought that only had to do with the whole dacron strip...

That's legal. If not, it should be. It looks like the only difference to the original window is the slight difference in the orientation of the fibres. That's not enough of a change in "essential characteristics".

The real problem is that there's no machanism of getting quick answers from actual ILCA measurers to questions like this. (And I have been told that it's actually only the chief measurer herself who is the only one who is authorized to decide these.)
