Disable formatting a region of code using directives

From: https://github.com/Microsoft/vscode/issues/33772

TypeScript Version: 2.4.0 / nightly (2.5.0-dev.201xxxxx)

Feature Request Add a way to disable formatting of a region of code. An example of this is js beatuify’s preserve directive:

// Use preserve when the content is not javascript, but you don't want it reformatted.
/* beautify preserve:start */
{
    browserName: 'internet explorer',
    platform:    'Windows 7',
    version:     '8'
}
/* beautify preserve:end */

The problem I see here that the whole idea seems not to be interesting enough to be considering / work on. I can not understand why, for us it is “must have” or no automatic formatter at all.

There are formatters in the marketplace that support this, but I don’t like many of them for various other issues. How’s the support for the native formatter going?

I wonder, what is the “More Feedback” that is expected? Can we have the flag removed?
