I also noticed that my son's school website allows virtual schooling, but it is limited in a way that would prevent him from, say, taking extra days off for bike-camping and making the work up online another day. Attendance is still mandatory, which I assume it also is in the schools you're referring to. If they are using virtual schooling programs to optionalize attendance, that would be a very interesting trend worthy of broader attention and policy adoption in other school districts. I doubt this is the case, though, because once kids find out attendance is optional, they begin looking for every loophole possible to skip school whenever they want. This is not true of all kids but standardized rule systems constrain the freedom of responsible people for the sake of controlling those that are irresponsible.
