[Tagging] Turn Lane Tagging?

I've been using the "turn:lanes:*=none;slight_right" & "slight_left;none" tags to indicate which side a new lane has been added on a highway when going from 1 to 2 lanes (sometimes "slight_left;slight_right" if the original lane is centered between the two new lanes). How else are people to properly identify which side the new lane is being added to? Take a look at this way ( https://www.openstreetmap.org/way/419799887 ) and take a look at the Bing imagery and look at the 'turn:lanes:forward' tag, and you'll see how this can, and would be valid. It's allowing the router to know that a new lane is being added when combined with the next way ( https://www.openstreetmap.org/way/419799886 ) which has the "lanes:forward=2" tag. It also allows the routers to properly tell people to get in the left lane if just ahead, there's a left turn they need to make.

I haven't seen "none;slight_right" as a value and am not sure how that should look different than "slight_right" by itself. However "none" is a value listed in the wiki  and I use it a lot as I find multiple vertical bars hard to manually count/edit but I can see and count things like "left|none|none" easier than "left||" when editing in JOSM.

I do need to know more about your concern: Is `none` as part of a multiple turn lane option documented anywhere?
I'm asking because we are adding turn lane tagging to iD this summer , so I have been thinking a lot about turn lanes, and I have read through a lot of wiki pages and discussion pages, and this is the first I've seen anybody using a tag like `turn:lanes:backward=none;slight_right`.
It's really important to me that I get this as correct as possible, because I can't have iD overwriting somebody's valid lane tagging. I'd like to be able to show visually what a tag like `none;slight_right` means on the ground.

I honestly think Mapbox needs to stop immediately editing ways that they think are invalid. I've seen several ways that I've work hard on, know are valid, and are being damaged by edits. The 'NONE' tag in turn lanes is COMPLETELY VALID!!!!
