Now I'm not sure if an "enum-like" zstyle is a good idea.

1) Should I check somewhere that the string value is valid (i.e. it's
either empty, or one of the predefined strings)?

2) Extensibility: I don't think there will be another different mode
that should be controlled by this zstyle. More likely, there will be
parameters like "prefer non-ancestor vcs directories or not". And IMO
they should have their own boolean zstyles, and not something like
`backend-choice closest-vcs-dir-prefer-ancestors`. And even more
likely, nobody will add anything there
