I think we just need to update docs that Acked-by is a *tool* mechanism
to help maintainers in their quest to find sanity in determining if a
patch is ready.

Clearly, if I don't know a contributor and they send an Acked-by, it
does not matter if was Donald Knuth (CS algorithmic lord), or John
Grisham (author of intense legal drama books), what really is of value
to the maintainer is the the qualitative appreciation over the
maintainer's own perception of the value of that Acked-by is going to
help the maintainer own's dreadful quest to find sanity in a review
process in answering if a patch series is ready.

An unknown developer to a maintainer, as qualified as they may be, could
provide an Acked-by, but the utlitiarian value is completely subjective
to the domain of review and so up to the maintainer's own critique. The
value in Acked-by is in helping the maintainer. There is a hidden
context of trust of behind the appreciation of maintainer's value of
a simple Acked-by.

A series of Reviewed-by tags over time on a subsystem can help a
maintainer appreciate the value of a future Acked-by by the same
developer. In fact the *more utilitrarian appreciation* for a maintainer
will be how often said reviewer is helping find *bugs* in previous patch
series, not how many Reviewed-by tags or Acked-by tags they use. The act
of finding real issues and thinking critically about the big picture
over and over of on different patchsets can help a maintainer garner
confidence in future Reviewed-by tags from the developer. Helping a
maintainer review patchsets and get authors to fix issues until it is
mind numbingly clear the patchset is ready is a way to help a maintainer
appreciate future Reviewed-by or Acked-by tags from that developer.

Since anyone can also provide a Tested-by, it does not mean that there
cannot also be subjective association to it as well. A Tested-by a reporter
of a complex regression is of most value. A Tested-by a random new developer
for the same complex regression may be meaningless to that same maintainer
unless the same original reporter also conirms the issues of a
regression are fixed.

Keeping a tag is not too important as well, we sometimes loose them even
for developers engaging daily, what is more important is *helping the
maintainer* on their quest to ensure proper state of affairs of the
patchset and to remain sane.
