The biggest end user change in this is that rule ordering matters a
lot less than it used to. If you specify content options in a rule,
multiple matches will alert on the longest singular content match.

That decision was made to most closely approximate how the snort rule
set was written with

most exact
less exact
catch all

rule systems
