I donʼt think that Alastairʼs point was about Microsoft not being innovative.
They simply allow old software to be used on new machines and Windows
versions, something that Apple reportedly does not on macOS.
However, as of Unicode support by keyboard layouts, the current advice
is that adding new functionalities to Windows 10 would keep them out of
reach for users of older versions of Windows, and new keyboard layouts
relying on them would be truncated for a still huge part of the users. That is
surely part of the “significant, perhaps insurmountable headwinds” faced by
“making significant changes to user32.dll”, Andrew Glass warned in 2015:
http://www.unicode.org/mail-arch/unicode-ml/y2015-m08/0042.html
Perhaps there could be a way to update older frameworks via Windows Update,
making an end with “limitation[s] of the Windows USER keyboard architecture”
that Michael Kaplan pointed in response to Karl Pentzlin, January 2010:
http://www.unicode.org/mail-arch/unicode-ml/y2010-m01/0030.html
Several discussions, in the past years, stated that we should be able to input
combining sequences using dead keys, a feature supported by macOS and Linux
natively, while Windows does not come along with that kind of support, although
this is recommended by TUS: “It is straightforward to adapt such a system to emit
combining character sequences or precomposed characters as needed.” (5.12, p. 222)
http://www.unicode.org/versions/Unicode10.0.0/ch05.pdf#G1076
In a 2015 discussion we/I also learned that Tavultesoft Keyman, now SIL, provides
all these features and is cross-platform, and had a free offer since long, now even
including the Developer tooling thanks to backing by SIL. Iʼm advertising this software
to advocate Microsoftʼs presumed position: For all that goes beyond legacy support,
we can rely on Keyman.
As a consequence, layouts that are to be shipped with Windows, such as the new
French, must stick with Windows resources (input editors are excluded by spec),
whereas minority languages needing extended functionalities can promote additional
software for support, as far as they are not expected to be supported out-of-the-box.
Hopefully we can now expect, by contrast, that Apple will add the missing toggle,
internally VK_KANA on Windows (Linux is reported to have it, too), to make it
available on macOS as well.

Marcel
