I may be wrong but my understanding of the discussion is that we are moving
towards a situation where LyX can only be installed if the latest MikTeX is
or has been installed. If this is so, then I have some doubts whether this
is wise and practical:

Precisely for these and similar reasons, it is not wise to require updating
MikTeX to the latest one. The latest one is usually not the one that was
current at the time LyX was compiled and the installer created. So we can
never guarantee that LyX works with the latest MikTeX, and therefore we
should not require updating to the latest one. Instead the procedure
followed until 2.2.3 works always. That is: there are two installers. The
first one installs only LyX, and it is up to the user to ensure that he has
a working and compatible TeX installation, whether that is the latest
MikTeX, an earlier MikTeX, TeX Live, or another one. The second one
installs LyX + MikTeX; users choosing this installer should be warned that
LyX may cease to work correctly, if they update or otherwise change the
MikTeX installation, and that MikTex should remain frozen.

Moreover there is now a TeX Live distribution for Windows, and if we
require MikTeX (that is, if the installer refuses to install unless MikTeX
is installed), this would be a great barrier to users who favor TeX Live.

I agree. Requiring to update to the latest MikTeX could possibly lead to a
lot of questions to the maintainer.
