Hello,

you seem to be the only mapper who consistently manages to create changesets with 10001 changes, although the maximum value should really be 10'000 changes, so one less. 
In total there are 103 such changesets since Mid-2019, out of which you have created 87.

I'm wondering if you're doing anything special in JOSM, like using single object uploads, maybe?

There could be something we need to double check from an API point of view. Let's see...
