It's observance more than anything else, at least in Britain. Many of our MPs have had their lives disrupted by this as much as the rest of us, and would like a return to normality (but crucially, only if optics allow, which they've almost got). That aside, Boris has no choice but to wrap this up soonish. The existence of the vaccine wipes out the bulk of the doomer cause, the Covid Recovery Group (Tory lobby group) are merrily twisting his cabinet's arm and have already got concessions, and of course there is the ever present threat of Farage. Panic and politicking got us into this mess, and the latter will help get us out.

Hell, fucking Hancock and Gove have come out and said "Easter" as when this farce comes to an end. We'll likely all be in Tier-1 months before then, as the jab brings the death numbers crashing down, which is what even the BBC sees as the most important result of it.
