My spouse and I got married "early" in the court system for a similar reason, in order to qualify for in-state tuition. However, we then had a proper wedding in front of our family and community a few months later, so I'm not sure it would really matter to the policy makers. Definitely helped drive home for us, though: there are three different marriages in a marriage:
There is a legal contract, that is important to people you have never met and will never meet, and, if things are going right, is never at all relevant to your actual marriage in any way except for how it lets you navigate government policy.
There is a social contract, that is important to everyone who acknowledges you as a couple (and also people who have never business seeing you this way).
And there is your actual relationship, which may be enhanced or degraded by the previous two elements, but is somewhat oblique to both.
