It's obviously entirely appropriate for Debian to make its own decision here
regarding what they want to support, but FTR the dropping of i386 was
largely not a "business" focused decision for Ubuntu.  While the ongoing
costs of maintaining a full port were a consideration, of equal concern was
the fact that we believed we would not be able to provide security support
for the architecture as a whole at par with other architectures, due to,
among other things, lack of adequate support from the upstream
kernel/toolchain community.  I'm not sure if i386 has caught up and now has
adequate mitigation for Spectre etc, but it definitely wasn't available on
an equivalent timeline as amd64.
