Just to be carefull: what's an easy 'automation' is for a dev is a big
hurdle for some plugin authors... And we have a lot authors already...

But authors have to update their plugins anyway isn't it? So how
countless is countless?

And we knew that we would break stuff anyway....

I'm in favour with 'looking into the future', but let us now walk too
much in front of the distro's. Packaging Qt will be the next step, and I
understand from Debian packagers it is a lot of work to do....

But how 'new' is 5.7?

Debian Jessie: 5.3.2
Debian Stretch: 5.5.1
Experimental has 5.6...
(we still need the building structure working)

Ubuntu?
Fedora?
Others?
