Question about regenerate product url keys per store view

[matthew99]

Hi, just a quick question. My client's data was migrated from 1.x to 2.3.5.
Lot of attributes lost the 'use default' setting that I now am resolving.

About 1800 products in 5 store views. He is not using different titles or url_keys per store view (or any attribute other than descriptions, really).

=> So is it wise to remove all url_keys for store views other than 0 (admin) and only regenerate for store 0?

In default all url-keys are regenerated across stores and since he is using a lot of product duplication while editing, I fear trouble in paradise with all these same url_keys across stores.
