what are these three?  They don't appear to be used below or mentioned anywhere
in the original .in file.

[ktyliu, 2017/01/29 21:22:14]

these three are from make_runtime_features.py;
the new json5_generator allows parameter defaults and valid values/types to be
specified in the config file rather than in the external .py script

some of these are referenced in the template, eg
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/build/scripts/...

[Rick Byers, 2017/02/06 20:46:24]

Can you try to add a comment summarizing what they do?  I guess this is a
pre-existing bug that the documentation didn't mention them, but now that you're
forced to mention them it seems we should say SOMETHING.  Worst case and it's
not clear, at least have a comment saying: "Used at ..." to at least help people
trace the code.

[ktyliu, 2017/02/07 01:12:18]

added comments for feature_policy and custom

conditions seem to be deprecated so I removed it here and in the tmpl.
Specifically
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/page/Runt...
has
// condition=ENABLE_NAME is used for wrapping features in compile-time
// #if ENABLE(FEATURE) guards.  These are deprecated and should all be removed.

[Rick Byers, 2017/01/27 22:17:01]

are bare strings allowed here?  I assume this is identical to:
{
  name: "CompositedSelectionUpdate",
}

right?

Personally I have a preference for the more verbose syntax to keep everything
regular and make adding/removing a status a smaller change.  But it's not a big
deal if you feel mixing the two styles is better.

[ktyliu, 2017/01/29 21:22:14]

agree the more verbose syntax is good for consistency and easier to add/remove
status

Fixed throughout

[Rick Byers, 2017/01/27 22:17:01]

nit: I'd find this a little more readable if the comments for an entry were
inside the block for that entry instead of above it.  Thoughts?

[mlamouri (slow - plz ping), 2017/01/28 01:10:44]

```
{ // MediaSession is enabled by default on Android only.
  name: "Media Session",
  status: "test",
}
```

maybe? Though, there would be benefit in having consistency across json5.
Probably more important than what looks good here.

[ktyliu, 2017/01/29 21:22:14]

I have slight preference for comment above the entry, in addition to Mounir's
point:
* comment above entry means it targets the entire entry {...}, whereas comments
inside the block can target a specific key/value pair
* multiline comment doesn't work as well if we do "{ // first line of comment"

for this specific comment, maybe we should define a parameter such as 'platform:
["android"]' rather than using comment only

[Rick Byers, 2017/02/06 20:46:24]

Ok, SGTM
 
Yes we totally should add that.  If you can quickly add such a OS-specific
parameter in (I think I saw something similar in another json5 file you worked
on?) that would be awesome.  If you'd rather leave it for someone else, then
I'll add it to my list to try to do sometime after this CL lands.
