The user community is not at all the same as it was for the first 2/3
of the past 15 years. Although windows uses .exe, .bat, etc., many
users don't see these anymore because recent versions hide extensions.
It is also unfortunate that Windows tends to capitalize file names
while ignoring case, so users will have "file1.tex" "File2.tex", etc.
but "\input file1 \input file2 ..." Furthermore, many mainstream tools
(R, Matlab) are widely used on both Windows and *x systems, so it has
become common to have multi-author projects where some authors are on
linux and others on Windows. When everyone was using lowercase ASCII
8.3 names without spaces (or UTF-8 encoding), most documents could be
formatted on either DOS or unix with little effort.

There needs to be some attention to document portability and
debugging. Just as some programming languages have "strict" flags to
help point out when language extensions are being used, TeX could have
optional checks for portable filenames and missing extensions.
