I cannot speak to how widespread it has been adopted, but the linux
(kernel) package for version 4.17.17 has been successfully built and
installed for ia64 under Debian ports.  There is clearly more work to
do to get ia64 rehabilitated, but there are over 10,000 packages
currently successfully built for ia64 under Debian ports[1].
