I’ve been in the “standalone” camp for a long time! I think there is some
“inside baseball” (https://en.wikipedia.org/wiki/Inside_baseball_(metaphor))
knowledge that would have someone distinguish between the two terms.
However, from the perspective of our end user docs, which is where we see these
terms the most, it’s standalone.
The werid use of both terms to me highlights that this is a problem to be fixed.
We currently have bin/solr start --user-managed option, but I think we could
easily make it be --standalone with a deprecated --user-managed in Solr 10.2.
