I don't check it manually!

Depends on the build process; it may be repacked from a clean checkout
of the tag.

Yes, but if the eolstyle is missing or incorrect, it causes problems
when developers use OSes with different EOLs.
Not only can it make it harder for the developer to use the file, it
can also affect the SVN diff messages, showing diffs where there are

Similarly if binary files don't have the correct mime-type; there have
been occasions when PDFs have been treated as text, which causes diff
messages to be huge and may cause some mail clients to bork.

There's no point for my use-case to both checkout the tag and export
it; once is enough.
