That's correct, there are no Kconfig symbols starting with AS_. But
still, I would like to hear whether there's a reasonable chance I might
convince other people to adopt my peeve.

The thinking behind that peeve is, basically, that where people
encounter a CONFIG_* macro they should only have to check the .config
file to see how that macro was evaluated in the build that was used.
