We ship raw JSON files in our package:

They could be easily compressed in order to reduce the installer size.

Note that the installer is supposed to also be compressed... so I'm not sure that it's a straight win to compress the files as shipped. Worth checking. I was mostly thinking that JSON can be a pretty verbose format, and I wondered if there was a better way of shipping this data.
Though looking at the file, it looks like it's about 400k, and I would expect better compression than down to 300k given how repetitive the file is...

Gzipping onecrl.json compresses from 400K to 63K
And intermediates.json from 1.3M to 400K, which is consistent with the comment about installer increase in https://bugzilla.mozilla.org/show_bug.cgi?id=1512451#c13 if the package compresses the data

I looked at CBOR, the binary format for which we already have libraries in mozilla-central, and the difference with .gzip is not huge.
It could have made sense to compress the files if they were read from disk, but since we package them in omni.jar it does not really affect the reading.
I'm closing this for now :)
