I don't know about anywhere else, or anyone else, but for ME it has morphed into a regular time to acknowledge that we are all isolated in one way or another (that is true even without lockdown!) and any contact with others is good. Recognising that many people are risking their own health to look after those most affected by the virus, and keep esential services running, is a good thing too.
That doesn't have to be labelled as virtual signalling, pooh-poohed as silly or dismissed as just window-dressing while wages etc are ignored!! Not everyone can campaign on the political front - or wants to. That doesn't make us second-class citizens who should be ashamed of admitting that we admire the key workers. We do what we do.
If you do want to do it - do it! If you don't want to do it, don't do it.
(to quote an old joke - "If you wanna buy a watch, buy a watch. If you don't wanna buy a watch, don't buy a watch. But keep your snotty nose off the watchmaker's window glass")
I plan to open my front door on a Thursday at 8pm for as long as I can.
