Thanks for your suggestion about an other wording.

I am curious if a second approach will become acceptable in the near future.

If you do not like the proposed changes for some subsystems so far,
I would appreciate another clarification:

* Could you tolerate them for any other software components?

* May I continue to inform involved developers about similar change possibilities?

Thanks for your software development opinion.

Do other system testers and Linux users care a bit more for corresponding
chances in improved software efficiency?
