Not being an "Importer" but long time contributor I agree to this one.

Additionally, I like the idea that the import will be done by hand (if
I read correctly). When all involved importing mappers do a good job
this will avoid a lot of issues mechanical imports inflict.

When you write a HowTo for the manual import process you must not
forget to mention the tool "replace geometry" from the plugin
Using this the users don't need to delete a lot of existing landuses.
On similar occasions users deleted "by accident" highways and
other stuff without realising. I only discovered that because a QA site
complained about street names of a town went missing.

Some musings on the workflow I used in similar situations:
* Use JOSM with the Plugins todo and utilsplugin2
* Open a file with landuses to import.
* search for type:way
* add the result to the todo list
* download OSM data
* double click the first item of the todo list
* have a look if near the landuse to import a landuse alreomasady exists
** if yes: check if the existing needs to be replaced by the new one for
   better accuracy
*** if yes: select both old and new landuse; apply "replace geometry"
	    – in the menu Tools 2 –> Replace Geometry
	    or press ctrl-shift-G
	    check tags for correctness¹
*** if not: check if tags of the landuse to import need
to be copied to the existing landuse


¹ useful: in the advanced settings set
TagConflictResolver.showTagsWithConflictsOnly to false
With this setup JOSM shows all tags which will be used on the resulting
way when replacing a geometry. You can keep or drop them.
