New Layer Request: USGS 3D Elevation Program
These two layers appear to be the most useful of the USGS 3D Elevation Program WMS services. One is a general hillshade which is useful for determining stream flowpaths, track roads through forested areas, and in some areas foot trails. The other is a dynamic contour lines layer useful as an overlay to assess land gradients at finer detail than scanned USGS topographic maps.
JOSM includes the hillshade layer as an extra option not found in this layer index, so there is some precedent for adding it. It also includes a contour layer from the USFS, although the 3DEP should supercede this layer as the USFS availabilty is only found in USFS-administered areas.

I'm not sure if this is related enough or should be a separate ticket, but I would have expected the current National Map USPS Topographic maps to be in ELI somewhere (rather than just what look to be scanned paper maps).
Map Server: https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer
I found it on the list of USGS Services: https://apps.nationalmap.gov/services/

I find it works fine in iD for me when I put a "Custom" background of https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer/tile/{zoom}/{y}/{x}
But I don't know if there's some nuance here I'm unaware of which is a reason it isn't available already as a background in iD.
Similarly, a bit more on topic for this, I can put in a custom background of
https://basemap.nationalmap.gov/arcgis/rest/services/USGSShadedReliefOnly/MapServer/tile/{zoom}/{y}/{x}
To see the shaded relief map that I think this issue is asking for.
I guess I'm just trying to understand why the USGS Imagery is in the list but the other USGS tile services aren't, and if there are any roadblocks to adding them. Thanks.
This is much better than satellite photos for identifying cliff edges (useful for rock climbing and hiking). Please add it!

That URL doesn't seem to provide the best resolution available?
This URL:
https://elevation.nationalmap.gov/arcgis/services/3DEPElevation/ImageServer/WMSServer?FORMAT=image/png32&TRANSPARENT=TRUE&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap&LAYERS=3DEPElevation:Hillshade%20Multidirectional&STYLES=&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
produces this imagery:
(though it sometimes doesn't load and the underlay is just black)
I've added the Hillshade Gray layer as the white background is not very clear sometimes, let me know if you need anything else.
I think the multidirectional hillshade is better than the regular if you're only adding one
Or maybe the multidirectional is misleading?
Unidirectional shows its more of a ridge and the cliff top should be lower:
