sorry, yes – it’s lacram_telenav.
The changeset that caught my eye is 67193952
I just don’t understand what they’re trying to achieve. There are gazillions of such intersections to be done if they head down this path.
I see that it is a member of a relation called destination_sign (3286190), which has lots of information about the signage on this exit. Do they need to have the motorway_junction tag to record these details about the signage ?? - and why wouldn’t they be using destination= ?

Subject: Re: [talk-au] highway=motorway_junction
I don't really see the point of motorway_junction unless that exit has a name or number (ref), however it's still valid per the wiki as on nodes at which you can exit the highway, I think to avoid putting it on absolutely every intersection we should reserve it's use for highway=motorway or trunk/primary which have grade separated exits.
So based on what you've said, it does sound okay, but if you could link to a few changesets that would help?
Is that username lacram_telenav instead of lacrom_telenav? Per https://wiki.openstreetmap.org/wiki/Telenav it looks like they are no longer working for Telenav, so if there is an issue or question we'll need to contact Telenav at eu-map-analysts at telenav.com <mailto:eu-map-analysts at telenav.com> for any questions.

lacrom_telenav has been adding highway=motorway_junction tags on exits from major roads around Perth – I think to designate destination signs. It is associated with “noref=yes”
The wiki says:
Use the <https://wiki.openstreetmap.org/wiki/Key:highway> highway=motorway_junction tag to identify a point along a <https://wiki.openstreetmap.org/wiki/Key:highway> highway=* with junction refs or names where it is possible to exit the highway onto another road. This is usually found along a <https://wiki.openstreetmap.org/wiki/Key:highway> highway= <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway> motorway, but is also applicable to other roads with numbered or named junctions including some <https://wiki.openstreetmap.org/wiki/Key:highway> highway= <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrunk> trunk and <https://wiki.openstreetmap.org/wiki/Key:highway> highway= <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dprimary> primary roads.
The instances I have noticed are not on roads with named or numbered exits, therefore I am thinking this tag is inappropriate. (I noticed it because it shows-up as an “e” on my GPS – which is a rendering issue I know)
The wiki also says:
<https://wiki.openstreetmap.org/wiki/Key:name> name=* for the name of the junction or interchange. Do not confuse the name of a junction with the destination(s) the junction leads to. In most cases worldwide, sign information describes destinations, not the name of the junction or interchange itself. If a signpost or indication displays destinations exclusively, this data belongs to <https://wiki.openstreetmap.org/wiki/Key:destination> destination=* tags, not the <https://wiki.openstreetmap.org/wiki/Key:name> name=* of the <https://wiki.openstreetmap.org/wiki/Key:highway> highway=motorway_junction node.
I tried messaging this user a week-or-so ago and have had no response.
What do people think about this tag? I don’t know what he is trying to achieve.
