The problem is that dependent packages expect them in /usr/include, and
have no way of knowing that they are elsewhere, as hdf5 uses neither
pkg-config nor its own -config script.

For example, try building octave-fltk:

http://cygwin-ports.cvs.sourceforge.net/cygwin-ports/ports/octave/fltk/

You'll get an error because octave/ov.h can't find hdf5.h.

Yes, but *every* package requiring hdf5 directly or indirectly will need
this, which is an unnecessary inconvenience.

You'll find it's best to stick with upstream packaging rules and
precedent set by other distros.  It will make things much easier for
yourself and others.
