Oh sorry, work is being done now

[benoitc]

i fully support that feature. Could you make it avaialble a s a PR? Also it should be made optional for now for legacy users imo. Thoughts?

[stofel]

I do not have a sufficient qualification, but I'll try

[benoitc]

It is impossible while travis check this otp_releases:

• R16B03-1
• 17.0
• 17.1
• 18.0
• 18.1

R16B03-1 not support maps.
