It was so obviously correct to me that I had a hard time arguing for it.
I don't think any of the objections were satisfactory, e.g. nobody has
asked, nobody needs it, the metadata archives are good enough, you can
already configure log messages to go to syslog.

I am still hoping to do something like this either as a part of
centralizing metadata repair (in progress), or as a part of a broader
suggestion that did get a better response but will take more work.  That
was to create a new log file and format in which every lvm disk change is
recorded.  https://bugzilla.redhat.com/show_bug.cgi?id=1455671

Everyone is encouraged to give their feedback about that in that bz, or
create an "issue" on the lvm github.
