A question recently came up as to whether highway=residential_link is a
meaningful tag or whether uses of it should be changed to some other
value (like highway=residential or highway=service).
This tag has no description in the wiki, though it is analogous to the
other highway=*_link types described on
https://wiki.openstreetmap.org/wiki/Highway_link .
There are only 23 current uses of the tag, but many others were recently
removed. By going through (by hand) the recent edits of an editor who
removed them, I've come up with a list of 58 more objects that used it
[1]. If anyone knows of a programmatic way of finding objects that
previously used a tag, I'd be interested to know it.
Of those 81 current and recent uses that I worked with,
* They occurred in North America (36), South America (30), Europe (11),
and Australia (4)
* 35 were added in 2015, 38 were added in 2014, and the remaining 8 were
added in 2010-2013
* I count 33 unique users that added the tag
* 19 of the uses had a value for name="*", 62 did not have a name
* Of the 36 North American uses, I personally think
highway=residential_link makes sense on 16 of them, while 12 should be a
higher highway=*_link and 8 should not be a _link at all.
highway=residential_link is not currently rendered in
openstreetmap-carto, and a request for adding it in February 2015 was
declined
(https://github.com/gravitystorm/openstreetmap-carto/issues/1280), due
to low usage and being undocumented. That bug mentions that it is
supported in various routing apps, and it WAS supported in the HOT map
style until that support was removed recently.
So the question is, should uses of highway=residential_link be edited
away, should they be left as-is (unless a different highway type is
clearly better), or should the tag be approved and documented?

generated by hand, and might have some mistakes. Also, not all of these
necessarily should have used the tag.

I think this should really be discussed in the tagging list.
I only know a discussion in Germany which came to the
conclusion that tags like unclassified_link, residential_link and
service_link make not much sense:
http://forum.openstreetmap.org/viewtopic.php?id=26083
The wiki doesn't mention those _link types as well, and my
understanding is that only major roads have a link (if link
in english means what we call "Abfahrt/ Auffahrt" in Germany,
I would describe it as a lane that allows to decrease/increase
speed.
