Can only speak to the US, but I don’t find this weird.
They want to keep up with the private sector - this is how ppl already interact with their employers, medical providers, their bank, even the damn library. But we all know it takes gov’t 10+ years just to get a website working… so it is scary to think what kind of old/insecure tech are using.
Most gov’t agencies here still maintain other forms of interaction, IE paperwork.
