LightmapSnapshot asset and source control

For my particular scene when the lightmaps are baked along with the lightmap snapshot, the snapshot ends up being 184.5 MB. Compared to the baked lightmaps at 18.7 MB, and the light probe data at about 1.1 MB for the same scene this is a significant asset. The realtime GI resolution was set at 0.125 which I think is considered to be 'very low'.

For now I've baked my scene without realtime GI.

My questions are this.

1) Is this LightmapSnapshot.asset intended to be managed under source control...
