Background

Standard JSON Schema was released as part of Standard Schema 1.1.0 (see standard-schema/standard-schema#134 ). This enables integration of any schema library that supports Standard JSON Schema.

Additionally, the current peer dependency mechanism has issues in certain environments (see #10122 ).
