Review Comment:
should this use `maybe_parse` instead of `try_parse` (noticed we're ignoring
the error from which on first glance looks unintentional)?

Review Comment:
I'm thinking we could skip the added API and have the caller call
`value.options.is_empty()` instead? since this is only a thin wrapper might not
be worth it
