> At the moment, the implementation of {{RowFilter.CustomExpression}} is tightly bound
to the syntax designed to support non-CQL search syntax for custom 2i implementations. It
might be interesting to decouple the two things by making the custom expression implementation
and serialization a bit more pluggable. This would allow users to add their own custom expression
implementations to experiment with custom filtering strategies without having to patch the
C* source. As a minimally invasive first step, custom expressions could be added programmatically
via {{QueryHandler}}. Further down the line, if this proves useful and we can figure out some
reasonable syntax we could think about adding the capability in CQL in a separate ticket.
