QtWebKit is not outdated yet. And security is least of problems when it starts 
getting older. The main problem is that it is slowly losing the ability to 
show modern webpages. The first causality was YouTube TV mode and anything 
else depending on Media Stream Extensions. More will join those once age sets 
in, but for EMail or wikipedia;  I think QtWebKit should be fine for a few 
years yet, especially for applications that continued to use Qt4.8 QtWebKit 
until recently.

Anyway, QtWebEngine runs a patched fork of chromium, and while we don't 
support OpenBSD, you are welcome to contribute patches to us.
