Please decide which edit you are proposing to run, you mentioned two 
contradictory algorithms.
And then actually propose it.

For the record, I oppose deprecating wikimedia_commons and removing it with a 
bot.

We would start to specify both commons_category and commons_file?

"Changesets will be kept small ie. country size bbox maximum." - this in my 
opinion far too large,
bbox should be far smaller.
