The feature flags list is not up to date

[bonamim]

Supposedly we should find the DRILL_TO_DETAIL flag available in this list:

https://github.com/apache/superset/blob/2.0.0/RESOURCES/FEATURE_FLAGS.md

How to reproduce the bug

1. Go to: https://github.com/apache/superset/blob/2.0.0/RESOURCES/FEATURE_FLAGS.md

Expected results

The DRILL_TO_DETAIL flag should be in one of these classifications:

• In Development
• In Testing
• Stable
• Deprecated Flags

Actual results

I can't find the flag.

Environment

• superset version: superset version 2.0.0

Additional context

I would like to know if this feature flag can be used in production environment.

Admittedly, that file tends to get updated for Major and Minor releases, and isn't reliably part of general day-to-day feature flag maintenance. Others (@codyml @michael-s-molina among them) may want to correct me, but I'd lump this into the "In Development" category. There are more bits (including additional chart support, testing, etc) still in the works. I'll leave this open until one of us can open a PR to mitigate this.

Also, a CC to @eric-briscoe since this is relevant to some organizing you were doing last week ;)

Opened a PR with this and all the others that are apparently missing
