So how do you mass-select exactly those objects you created based on a
given source (mass-selection was the topic of the mail I replied to)?

Regardless of mass-selection, "I used npe, landsat and survey" is a
valid property of the changeset. It may be possible to give more
detailed information, of course. But most mappers don't add source tags,
and a changeset source would provide at least some information. You can
continue to add source tags to individual objects if you think it's
worth the effort - it's your decision, as with all tags in OSM.
