In my experience I'd say many, otherwise we should be currently seeing more
metadata and open formats in practice and that's not happening.
There is nothing wrong with BPs being quite simple and evident. The good
thing of BPs is precisely their guiding and reference character.
In addition, there is nothing preventing us from going deeper through
implementation techniques with specific technologies.

Then you can provide specific implementation techniques for those.

Yes, asking for LOD support is usual when you work on a LOD project or
environment and quite the opposite when not. Have been working on around 50
different OD projects during the last 6 years and I think that maybe just
10% asked for LOD techs. As another example I have recently participated in
the evaluation of 300+ proposals for OD based businesses and only roughly
between 2-3% were planning to be using LOD at any extent. In general I
noted that LOD is something people is not usually screaming for except in
some specific scenarios.

This looks more like a quite specific guide than a best practices document,
no?
I think this would be a great idea as an additional WG note with an
implementation example, but not as a replacement of the BPs themselves.

I think some of the most popular recs at W3C in the past were such "general
advice" e.g. WCAG, MWBPs...
I think that making BPs generic and tech neutral is a BP itself.
I think that having good generic BPs is also compatible with much more
specific advice (in the form of implementation techniques).
I think we should be only focusing on LOD if we agree first on modifying
the charter and the document name and scope.

Best,
 CI.
