IIRC, this sentence is here because Hibernate Search used to package
the analyzers extracted from Solr in a specific Jar. It was removed in
favor of a dependency to Solr jars when they were pushed to Maven not
so long ago.

IMHO, the important word in this sentence is the "required" in "all
required Solr dependencies": stempel, ICU and smartcn aren't
required at all: if you want these specific analyzers, you just have
to add a dependency to them, which isn't surprising.

It doesn't seem like a bad idea to be consistent with how Lucene have
rearranged their analyzers and to include all the lucene-analyzers +
the Solr machinery used to wrap them.

I think it's worth a note in the release notes though if we go this way.

I'll go create a JIRA as you asked.
