I believe you will be ok.
The adjudicator says
Long story short – The adjudicator has ordered the installation in the location that I have requested and found the SM unreasonable in their refusal of my request.
So a bylaw that conflicts with a ruling would be very unlikely to be enforceable and that is the crux of it. They can pass any number of bylaws if they have the numbers but their (of the bylaw) validity is not checked on registration it is only tested when they go to adjudication.
When you won at adjudication you must have had a valid case and that case hasn’t changed just because the Strata have moved the goal posts. But as Whales says get it installed before the new bylaw and then they would have an even harder battle.
