The topic of this very thread is how to avoid dropping support for 32bit architectures. So people clearly want to continue supporting it. > As Sam has said multiple times, what's much more likely is that the > set of packages that can't be built on native packages on 32-bit > platforms will grow over time.

It might matter pretty soon: for generic-purpose systems one almost always want to be able to use a web browser; even various embedded systems do. However web browsers are one of the most heavy packages to build. > At least initially, the simplest way of dealing with the problem is > that maintainers will simply not build their package on 32-bit > platforms. I don't think we want this to happen if we want to continue supporting 32bit systems. But using a 64bit toolchain in an otherwise 32bit userland as the thread suggests we now really should start looking at will avoid this. It will probably take a few more years until we have to worry about being able to run browsers in 32bit... But I would hope that most people understand that using 32bit for new generic-purpose systems is not future-proof (and hasn't been for a while); even phones have started to move to 64bit systems a while ago.
