One more exhaust part performance enthusiasts will remove from their exhaust systems in the name of performance. Sigh…
After removing the catalyzed version maybe to performance buff can sell it to reclaim the catalysts. 
I wonder how much this will add to the cost of new cars. If it is pretty much the same materials as in a catalytic converter, this could amount to a thousand dollars or more. Maybe they could design an all in one unit to do everything.
When I hear “filter”, I think one more thing that has to be replaced periodically. I wonder what that frequency will be and how much it will cost.
A GPF will regenerate just like a DPF.
And will require periodic cleaning either by pressure washing or pulse cleaning.
But shouldn’t require replacement.

Do we need to be ready? Are you aware of some pending legislation that will require their adoption?
Presuming a GPF produces cleaner air better than the alternate methods costing similar amounts, the cleaner air to breath seems like it is worth the compromise. Especially if the gadgets are configured so they can be easily be serviced by diy’er owners.
good luck with that.
The car manufacturer who provides that will get more sales than the ones that don’t .
I have not been ready for anything since the 80’s. That is why I use a shop for car stuff
No manufacturer is going to care about ease of repair for an emissions control device that likely is a life-of-the-car item.
And next to no purchaser (except one, I guess) is going to care.
I care about reliability, NOT having to replace that stuff, not how easy it is to replace.

“… Pick wisely, and you can enjoy years of low-cost trouble-free driving. Pick wrong, and your car could wind up being a money pit that drains your wallet month after month.”
Is this device warranted for the life of the car? Free repair/replacement if it fails, diagnosis, parts, & labor? If so, then I concur, it shouldn’t affect sales, much.
That article talks about maintenance and reliability. Again, nobody cares about how hard the evaporative emissions cannister is to replace, to pick an example something like the GPF. How could they know that, anyway? You’re proposing an impossible standard: all parts of the car should be easily replaced. How could anyone know that?
Someone buying a used fixer-upper might care, but at that point the carmaker won’t, they’'ve already sold the car years ago.
