I'm surprised it isn't obvious.  Think about it this way: CVS had basic 
EOL support and SVN gave slightly better support, and we leveraged this 
support in both those tools.  The end result is a very clean repo with 
consistent line endings and a distinct lack of developer friction 
between the platforms.

Your position seems to be that we *never* needed EOL conversion, 
especially in SVN which offered decent hooks, and that having a source 
repo with a mismatch and unpredictable line endings isn't really a 
problem at all.

Even just at face value, it seems clear we have taken full advantage of 
that feature for around 1.5 decades, so to suggest we never actually 
needed it, or at least don't need it now for some reason, seems slightly 
disingenuous...

Cheers,
