Consider enabling createDefaultProgram

[JoshuaKGoldberg]

🚀 Feature Request

Forking conversation from #738 (comment):

Also, I have seen this fix on many other issues and wonder why it doesn't get placed on default if it fixes many issues.

In .eslintrc.js inside "parserOptions" placing

'createDefaultProgram': true

Seems to fix a lot of eslint issues with my IDE.

Existing Behavior

createDefaultProgram is not mentioned anywhere in this repository.

Change Proposal

Should it be included in the default output configuration? If so, should it be always on, opt-in with a flag, or opt-out with a flag?

Investigation required!

I don't think this option should be enabled by default. From the README:

Using this option will incur significant performance costs. This option is primarily included for backwards-compatibility.

This performance hit was true in practice in the Blueprint repo, where we initially enabled it and then disabled the option. So I don't think tslint-to-eslint-config should encourage its usage.

That's a very good reason not to. Thanks!
