Windows/ME was never popular, even when it was released
As I understand it, that "WinME" label is a catchall that includes the
MS-Windows 9x line, and "0.01%" is so small that I doubt whether it is
statistically significant. In practice then 9x line has transitioned
from unsupported (ten years ago) to on-its-way-out (five years ago) to
dead (now, almost everywhere), and any old decisions that assumed 9x's
viability are now obsolete.
In GNU projects, we typically stop worrying about an underlying platform
when its original supplier stops supporting it. For example, Emacs no
longer worries about IRIX because SGI stopped supporting IRIX in 2013.
Although MS-Windows 9x is special partly because it was so popular long
ago, Emacs need not support 9x indefinitely, and Emacs's documentation
should not give Emacs users the incorrect impression that 9x is still a
live platform.
