I also expect that a lot of users (of m68k kernels) are never going to
get the benefits as they are already stuck on older userspace because

understanding than me of what m68k hardware is commonly used these
days, and how constrained that is in practice.
I second that - currently bisecting to find out what makes my extremely
RAM constrained m68k system fail to boot or run anything past 6.9-rc4
(sysvinit, not systemd).
As cloud instances multiply, that small quantity of lost RAM gets
multiplied. So it appears that small systems aren't so strange, even after
they become unprofitable...
Yes, who doesn't know the cloud instances with 64 MB RAM. Those are today's standard.
Much as I appreciate Adrian's efforts to keep up with user space
development, I won't be in a position to help with an ABI change.
Bloated m68k packages will continue to work -- given emulators that run
faster with every hardware upgrade. But how would such a distro add value?
You can easily upgrade Amigas to 256 MB or more these days. The aftermarket
provides a lot of affordable upgrades these days.
I don't mind if Gentoo ships a separate profile for (downstream) ABI
experimentation, leaving the default m68k profile on the standard ABI.
The Gentoo developers will be glad to hear that you don't mind. Do you think
they need a written permission from you?
And if Debian wants to switch ABI entirely, I won't object further, I've
said enough about the associated risks.
So I'll just reiterate that I'd rather see more collaboration instead -
1) among all small systems ports, to try to alleviate Debian's package
dependency problem
That dependency chain comes from upstream, not from Debian.
2) among all developers working on non-commercial architectures, to
improve the GCC Rust frontend
GCC Rust uses parts of the upstream Rust code, so you can expect the same
problems there as well.
3) among all 680x0 developers interested in the NetBSD ABI
The alignment issue affects NetBSD as well.
4) among all users of EOL'd hardware, so that value may continue to be
extracted from it (thanks to the efforts of Debian and Gentoo devs,
among others).
Software will run faster with 32-bit alignment, not slower.
