It's quite doubtful it will keep working.

Well people keep saying this for years now. When it stops working we'll make statements like "root breaks access to Netflix and Banking apps". But since it doesn't at the moment, everything is good.

But it does break them. That's what happens when you enable root, they break.

You have to use pretty shaky workarounds to trick them, and there is a known way to make those workarounds impossible.

As far as I've understood, the safetynet fix makes use of a feature which only exists for comparability reasons, so that old devices don't get locked out entirely. When there aren't enough old devices around anymore, it will likely stop working.
