AFAIK every other linux distro shipping with or providing options for LibreSSL also switched around the same time frame, e.g. Gentoo dropped all support for it.

AFAIK every other linux distro shipping with or providing options for LibreSSL also switched around the same time frame, e.g. Gentoo dropped all support for it. It's just not feasible to build 3rd party software (that are targeting OpenSSL) with it anymore (obviously, if you targeted libressl specifically, there's no problem, but almost nothing does). Maintainers have just gotten tired of writing giant patches to get things like Qt5 working again.
