I wouldn't drop Excel (97/2003 or 2007) export just like that, unless
nobody seems to use it of course. ;)
F.e. : It's very useful to export data from a database using a query
to an excel-sheet to use for further analysis (or other uses).
Since both Excel 2003 and 2007 (and other versions) are still widely
used, I don't think that any of them can be dropped.
It's true that CSV-export can be used for that, but it would mean an
extra step to convert to Excel.
I had a brief look at the PHPExcel library yesterday and I think it
will be possible to remove a lot from the library that we don't use,
including the OLE part (which would solve the license problem). OLE is
used to link objects (like an excel sheet or a graph) to other
documents/applications, but we don't use that when exporting to Excel

True, but the phpMyAdmin package has to be installed by someone
anyway. It could be part of the installation procedure to install the
PHPExcel library somewhere.
But then again, this might cause compatibility problems with future
releases of both phpMyAdmin and PHPExcel.
