[Tagging] history discardable ?

[Marc_marc]

Hello,

a long time ago, some tools add history=* to describe how a revert was done.
the current method is a changeset tag, for example
created_by=reverter_plugin;JOSM

however there are still 42000 occurrences in the database and this
number increases every time someone split a way.
e.g. with https://www.openstreetmap.org/way/8105642 tag added in 2008,
but put on any splited way from it
https://www.openstreetmap.org/way/508259115/history
besides the uselessness of this information as a not-a-changeset tag,
it leads to absurd situations with "recovered from version 4 on objects
starting at version 1".
I therefore propose to declare this tag discardable so that this tag
disappears during a modification instead of being propagated.
if it makes consensus, I will open the tickets josm, id, ...

What do you think?

Regards,
Marc
