I was going to suggest something similar.
I'm still being cautious because of worries about long Covid, which is more prevalent than I'm comfortable with. Quite likely my view is affected by my eldest child having had a similar illness (ME/CFS) which has blighted their life for seven years, since the age of 15. I really really don't want anyone else in the family to suffer like that.
We also have the luxury of being able to be cautious without it affecting our lives excessively. DP works outdoors and I home educate our youngest. She and I are still sticking with all outdoor activities, which is not much of a hardship. She plays with friends every day, just as she always has. Through the winter we carried on with bushcraft, tennis, hockey, climbing, and constant playing in the park. She sees friends in their garden or hers or in the nearby woods. She does do a few things indoors which she loves enough that I think the risk is worthwhile.
I only know a few people who are home educating primarily to avoid Covid or other illness, but there have always been a few in the home ed community. For example, one little girl with cystic fibrosis would land in hospital for a couple of weeks every time she caught anything at all, so her parents found it best to withdraw her from school. She usually played outdoors, or saw just one or two friends at a time indoors rather than being crowded in with dozens of other children every day. Sure, she still got ill, but the odds weren't so bad that way and she didn't get ill so often.
Playing with other children is great for kids' social development, but that doesn't have to be indoors in large groups. It is quite possible to avoid such environments indefinitely and to have a good social life if you are happy to home educate.
I'm not entirely convinced by the view that kids will catch lots of bugs and be constantly ill at some stage in their lives, so you may as well get it over with when they're tiny. That hasn't been the case for my eldest (who went to school for a while in Y5 and later to uni) or the other home ed kids I know, many of whom started college at 16 having never previously been in crowded environments on a daily basis. Mixing with smaller numbers of people doesn't seem to have stunted their immune systems as people fear it will.
