I have not used OSs where binary mode matter for many years, but
esentially I do the same.

Lots of people do this to me, and it is correct. I normalize
everything before ingestion, either on the fly or beforehand. What I
do not not normally do is store the file as it comes, I store it in
the local text format, which fo me is always unix. ( It may hit the
disc on windows native format on a staging area, but when I  put it in
its place I normalize it, so only the upload process needs to worry,
and I also get rid of win-1252, BOMs and other things on the fly ).
While it has CR it is a temporary file I got from the net, when it
goes to a place where it becomes a config file I already have it
normalized, so every local tool can treat as a text file. This is
needed as in Linux you use a lot of tools on config and other things,
and its better to have them work ok ( not that they care, normally the
extra CR is just a trailing space which does not hurt, but better zap
it ).
