Yes, I don't see the point of maintaining technical debt just for the sake of it.

The security environment in 2026 is such that legacy unmaintained code is a very real security risk for obscure zero-days to exploit to gain a foot in the door.

Reading through the list I don't see it being an issue for the overwhelming majority of Linux users.

Who, for example, still uses ISDN in 2026 ? Most telcos have stopped all new sales and existing ISDN circuits will be forcefully disconnected within 3–5 years as the telcos complete their FTTP build-outs and the copper network is subsequently decomissioned.

Most TV and radio stations.

Do they use it via mainline Linux kernel's ISNDN drivers though (and not something proprietary)?

I doubt it. And as I said, telcos have ceased new sales of ISDN and will be shutting down copper networks within 3–5 years.

Therefore if there are still TV and radio stations still using it, they will be forced to stop using it by circumstance, i.e. they will find their ISDN will cease working after the telco shuts down the kit in the exchange.

		You can doubt it all you want, ISDN is used internally in broadcast all over the world. Telcos shutting it down has nothing to do with them and won’t affect them. Losing support in software however, does.
