Changes between Initial Version and Version 1 of Ticket #27200, comment 8

initial	v1
40	40	I'm just struggling a little to understand the intention here in multi-db scenarios where an update on one db requires another update on another database. If the Django team has a clear intent then it just needs a more definite explanation in the docs (in my opinion).

	42	edit: I'm in the middle of some stuff right now so sorry if this feels a bit scattered. Since I'm allowed to access models in other apps inside a data migration, what if those models don't have complete database overlap. Or is the intention that if that's the case I'm supposed to only read the other model but not write to it, since allow_migrate is this context is in an `app_label` context and should only loop over some of those databases? I'm not sure if this was super clear so let me know if I need to rephrase that.
