Testcafe's tsconfig settings are different from standard tsconfig defaults and some are undocumented.

What is your Scenario?

I've been asked to break up the trade-offs listed in #7978 (comment) into separate issues so they can be discussed individually.

What are you suggesting?

TestCafe passes the following options to the TypeScript compiler unless you override them:

Option	Value
allowJs	true
emitDecoratorMetadata	true
experimentalDecorators	true
inlineSourceMap	true
noImplicitAny	false
pretty	true
suppressOutputPathCheck	true
skipLibCheck	true

These aren't always aligned with tsconfig defaults. This can make your tsconfig appear strange relative to the typical tsconfig: if you want to remove one of these settings, you add the property.

You can override some but not others. e.g., you can't modify target (at least, I think that's why I errors/warnings about it sometimes). If I'm correct about testcafe being the source of those, I don't think this table is comprehensive: target isn't mentioned.

I don't even know what suppressOutputPathCheck is, as it's not officially documented.

What alternatives have you considered?
