These don’t yet exist. That said, Paris just took its industry out of the running for building that future.
Setting a low- or zero-carbon threshold for these flights would have been a future-proof solution. (Or an exorbitant carbon tax, to align prices between trains and planes.) Altogether, this looks like protectionism in anticipation of the TGV’s upcoming expansion [1].

I'm afraid, no, not "soon".
And when then do (I would probably bet "in 10 to 15 years", and I would absolutely bet "later than you're optimisticly hoping", because that's what the people making the planes are saying [1] [2]), then the bans won't make sense, sure. At some point.
But the emphasis is _AT SOME POINT_, where the commercial fossil fuel propelled planes are travelling and emitting _RIGHT NOW_. The best time to reduce the number of flights was 20 years ago, the second best time is now.
MEANWHILE...

We have a big plane industry, Airbus is _very_ actively working on EP (no idea if they will achieve anything, but, hey...)
I doubt this law should affect them much - their target is probably to "fix" private jets and very short trips rather than intercities, anyway.
I'm pretty sure that if they ever find a way to make fully electric flights between the _three_ routes that are canceled by this law, then the _three_ routes will re-open.
The question now is whether this is opening the road to banning more routes (the CDG situation is _really_ absurd, and will probably be a political bargaining chip in the future), if other countries will copy the idea, if the overton window will shift to banning private jets, etc...
Fairly symbolic at the moment, but if you believe in the "small steps actually taken vs ever-postponned revolution", that's a thing.
Airbus is (perhaps intentionally) untouched. It's the space below them, which is being aggressively pursued by start-ups, that's being cut off at the knees by Paris.
