I have much more serious issues with this change: it is an
incompatible change in a long-standing behavior, which AFAIR was never
discussed.  Worse, it loses information: files that are read-only
(something that _is_ supported on Windows) are no longer marked as
unwritable, and executable files (not marked as such in the
filesystem, but still a clearly existing attribute that we support) is
not shown as such, either.

I think if anything, this should (a) show 3-4 letters instead of just
d or dash, i.e. drwx for a writable directory, -r-- for read-only
files, -rwx for writable and executable files, etc; and (b) be an
opt-in behavior, i.e. we need a new defcustom for it.  In its current
form, this change is not acceptable, sorry (and neither is the way of
installing it without any discussion).
