My pet peeve is with the still half finished look, it jumps out as really garish now to when you open the dev tools and see the clashing styles or the bookmarks/history dialog that hasn't been updated in ages.
Not to mention the white title bar in some dialogs even with dark mode enabled.
The Proposal for encoding the Phaistos Disc characters[1] lists the motivation behind including it (and rebutes some counter arguments). Principally, lots of publications discussing the Phaistos Disc would use it:
> Phaistos Disc characters, whether syllables, or letters, or board-game dingbats, have historical and cultural significance, as attested in the large number of publications dealing with it. As noted above, the Wikipedia has articles about the Phaistos Disc in ten languages. The 30+ documents listed in the bibliography in this proposal are by no means the only documents printed which deal with the Phaistos Disc characters. The English Wikipedia article gives Phaistos Disc characters inline in text as well as in tables (Figure 8). Other documents exist which present the Phaistos Disc characters either inline (Figure 8) or in tables (Figures 1, 2, 5, 6, 7). It is true that the image of the Phaistos Disc itself is easy to represent with simple drawing (see Figure 3) but the discussion of its characters inline in Latin text is not.
