Discard converted_by?

[naoliv]

Since JOSM already removes created_by and other tags while modifying some objects, shouldn't converted_by also be discarded?

I think this should be discussed before on a bigger audience e.g. forum, tagging mailing list what this tag is about and if it should be deleted.

[naoliv]

Right.
I will ask on tagging.

[stoecker]

That was never a standard tag. And it's only about 100.000 times in the database. On the other hand some of the stuff we drop has much less remaining entries (e.g sub_sea:type). There aren't any useful values for that tag, so probably dropping it is ok.

[naoliv]

I only got two answers in tagging.

One yes: ​https://lists.openstreetmap.org/pipermail/tagging/2016-September/030232.html
One no: ​https://lists.openstreetmap.org/pipermail/tagging/2016-September/030233.html

In 11064/josm:

fix #13682 - silently drop also converted_by

[stoecker]

In 11065/josm:

see #13682 - silently drop also converted_by - remove duplicate

[stoecker]

Then we do it the JOSM way and simply decide ourself. And get the blame for it when somebody complains. Anyway we already handled it as throw away tag in the checks.
