My motivation is that some of those dependencies (especially for DOCS)
are quite big (docbook for example). Under no circumstances do I want to
waste hours of time building those and all of their dependencies.

So, again, silent DOCS/NLS/EXAMPLES when additional dependencies are
involved is very, very undesirable.

NLS does often mean gettext, yes.

If that is a concern, we can actually count how many ports will be
affected by such a policy. I expect the number not to be high.

For example there are only 13 ports with NLS in the whole 'lang'
category. Out of those 13, only 4 have no other options and will require
a config dialog under the policy I propose.
