QtWebEngine seems to require libxml2.so.2.

However, libxml2 v2.14 was released recently, bumping the soname:

Binary compatibility is restricted to versions 2.14 or newer.
On ELF systems, the soname was bumped from libxml2.so.2 to libxml2.so.16.

Due to that, I'm now unable to e.g. run the simplebrowser example from Qt binaries on Archlinux:

./simplebrowser: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory

As a workaround for Archlinux there is a libxml2-legacy package.

But probably libxml2.so.2 should be shipped with the binaries, similarly to what's done with ICU as well?
