Will this turn into another leaky homes type situation in the future? Probably.
Funny you should say that :-)
We've just moved back into our ex-leaky home. I was lying in bed last night when I had a real "DOH!" moment. When we had all the cladding off, I took the opportunity to get structured ethernet cabling installed throughout the house. I gave a cursory thought to the ONT location when we finally get Fibre in my street in 2018, but no more than that. What I SHOULD have done is had something installed to make it a doddle to blow the fibre up to where I want the ONT to be (2nd story office, directly above the curb-facing garage). Too late now, but I'm hoping they may be able to use the existing dedicated ADSL port to pull it through when the time comes.
In my defence, there were so many moving parts to this project, and such a tight budget to it too. And I am still smiling from ear to ear that I finally have decent structured cabling coverage throughout my house.
