They had a ton of time indeed, but they didn't cover this particular eventuality. It's literally in the same post. Perhaps give it a read?

  Since launch, we have had four smaller measurable micrometeoroid 
  strikes that were consistent with expectations and this one more
  recently that is larger than our degradation predictions assumed.

This still doesn't indicate anything.

It doesn't say how much bigger.

My point I'm trying to make: the original comment indicates to me that we need to worry. For me it conveys much more speculation than I think is reasonable right now.

For example they were also not expecting to have such a great optical resolution.

It does indicate something. It indicates that

The delta matters, but no matter the delta, the fact that it defied expectation stands.

How does one even collect information about the probability of being hit by something that big in space ? They counted hits on things (ships) that came back from space ?

[Termitiono]

The lagrange point itself has a probability how realistic it is that something can be cought in it / if it stays there.

There are other points were stones collect like l4 and l5.

Then we have Hubble (and over 100 others as a benchmark, a few ships/missions like to the moon and Mars.

Herschel space observatory was also on l2. There is a wiki Artikel called 'list of objects at langrange points'

They've launched flat plates made of aerogel to capture orbital debris.
