Why and when? When it is my job to integrate stuff from a namespace with a
software system for delivery, for example, and the result is going to be
used by others. They have their own rules and expectations, not always
tolerating continuous (wait for) delivery of whatever I thought could be
excluded for reasons of minimization, at this time.

If they prefer convenience, I have no choice. If the namespace is tightly
coupling what is on it, I have no choice.

Depending on the chosen meaning of “relate”, pieces wise control over
source text creates opportunities.
