Dear Maintainer,

currently, libhdf5_serial.so compiles the s3 Virtual File Driver (VFD)
support into the library itself, which leads to inflated .so
dependencies: libcurl.so pulls in about 20 other (networking, crypto)
libs -- below is the output from lddtree.

Starting from version 1.13.0, HDF5 should support virtual file drivers
(VFDs) as plugins [1], similar to already existing filtering plugins.

This report suggests to package the S3 VFD as a plugin, if possible,
considering that most HDF5 users won't use s3 and the number of
indirect dependencies is high.

Thank you for considering this option. Your packaging work is
appreciated.
