Minimum translation percentage for Plasma 5 release

[Albert Astals Cid]

Hi, in the 4.x world we have something called "Essential Packages" for 
translations that is basically a set of minimum percentage of some files that 
you need to get if you want the whole translation of your language to be 
released with the 4.x SC.

For KDE Frameworks we have decided to not have a minimum of translation. Each 
Framework will ship the translation files it has available.

The question here is if we want it or not for Plasma >= 5.1.

If we only ship languages with say >= 70% we ensure that the shipped languages 
have a reasonable number of translations (one can't ensure quality).

On the other hand a hard limit is also a bit "unfair" to users, if the 
translation drops to 69.5% because the translator went MIA, they will stop 
getting the translation. Also it makes it harder for smaller teams to get 
contributors, since the moment we drop it, it gets less visibility and thus 
it's harder for the small team to get new contributors to help them reach the 
required percentage again.

So I am leaning towards "no minimum", but I certainly welcome all comments and 
am open to change.

Opinions?

Cheers,
  Albert
