Alessandro Solimando commented on CALCITE-6293:
-----------------------------------------------
[~timgrein] it's usually useful to share more details on why you need
normalization of OR expressions, someone might have alternative ideas on how to
handle the problematic cases, if any, it's good to try and have this kind of
discussions in Jira before going too far into the code in general
