Review comments at @docs/migrate-from-v1.md:
- Around line 666-667: Clarify the on-demand validation section near the
`validateField` mapping: state that `FormGroupApi.validate(signal)` runs
validators for fields in its group, while single-field validation is configured
through field validators; retain the existing `triggers` and `watchFields`
mapping.

The list is a bit eager, but that's fine. If we recover methods from v1, we can delete them out of this list alongside the PR.
Thanks!

🎯 Changes
Closes #2420.
Adds a "Removed and renamed form methods" section to
docs/migrate-from-v1.md. It maps each v1FormApimethod missing from v2 to its v2 replacement:moveFieldValues→moveFieldValuesetFieldMeta,getFieldMeta,resetFieldMeta→FieldUpdateOptionsonsetFieldValue(markAsTouched,markAsDirty,causeValidation),field.meta,resetField/field.reset(), orreset(form.state.values, { updateDefaultValues: false })validateField,validateAllFields,validateArrayFieldsStartingFrom,validate(cause)→ validatortriggers/watchFields,handleSubmit(), and a note thatform.validate()runs form-level validators onlygetAllErrors,setErrorMap→form.state.errors/field.errors/isValid, and errors returned from validators,createValidationError(...)orserverStatedeleteField,getFieldInfo,getFormGroupMeta,parseValuesWithSchema(Async)It also maps the v1
setFieldValueoptions (dontUpdateMeta,dontValidate,dontRunListeners) to their v2 equivalents and adds a pointer to the quick checklist.replaceFieldValueis left out because #2418 already tracks it.I checked the behavioral claims against
form-coreonalphawith a throwaway test, not included in this PR.Please confirm: v2 has no public way to validate a single field, or all fields, outside submission. The guide says so and points to
triggers/watchFields/handleSubmit(). If an imperative replacement forvalidateFieldis planned, I'll update the section.✅ Checklist
