I could read it also as FOSSil with FOSS connotation (free and open-source software). Also, a single-file repos are akin to a historical artifacts of developers work and ideas surviving through the times. Don't we all have tons of projects sitting in their various state of abandon under the work directory? Well, Fossil lets us sweep the shame and organize these 'fossils' in a neat set of individual Fossil repo files in a grand /fossils or such directory. All repos 'readily' waiting to be respawned into a fresh work directory checkouts to perhaps offer some chance of completion. By the way, looks like the Fossil repos can be queried directly without a check-out into a separate directory. It simplifies the review of the history and contents.
