Does strictTemplates option consider to be stable and recommended to be enabled for new Vue Typescript project?

I enable it to find undeclared components. After looking into the docs, I feel it's a very useful feature to prevent small mistakes and catch them during compile-time.

Basically yes, except that checkUnknownProps and checkUnknownEvents may not work well with component libraries.

What do you mean "not work well"? Are the behaviors negative compared with not enabling it? Like lead to unknow errors. Or it could still works and is just not strictly typed.

If they still work without negative behaviors, I'll start to send PRs to enable strictTemplates by default for Vue frameworks.

If not, how about having a "safe" set of strictTemplates? and we could make that default. I really like the check unknown components behavior and hope the community ccould benefit from it.

For component libraries that use vue-tsc to build types, if fallthroughAttributes is not enabled during the build, the component will not treat the attrs of its single root element as its own props. In that case, when users enable checkUnknownProps, they will get type errors for HTML attributes that would otherwise be able to fallthrough to the component's root element.

Additionally, fallthroughAttributes configured in user space cannot take effect on these components that have been built. Unless users use this workaround, they will not be able to fix these type issues.

I think a safe subset of strictTemplates could be checkUnknownComponents and checkUnknownDirectives.
